Li-ION/POLYMER 1CELL PROTECTOR NO. EA-215-230201 OUTLINE The R5403x Series and the R5405x Series are high voltage CMOS -based protection ICs for over - charge/discharge of rechargeable one-cell Lithium-ion/Lithium polymer excess load current, further include a short circuit protector for preventing large external short circuit current and excess charge/discharge-current. Each of these ICs is composed of four voltage detectors, reference units, a delay circuit, a short circuit protector, an oscillator, a counter, and logic circuits. The output of Over-charge detector or Excess charge-current detector switches to "L" level after internally fixed delay time, when discharged voltage crosses the detector threshold from a low value to a high value. They have two types to release Over-charge detector. The one is called "Latch type". The output of C OUT switches to "H" when a kind of load is connected to V DD after a charger is disconnected from the battery pack, and the cell voltage becomes lower than over-charge detector threshold. The other is called "Auto Release type". The output of COUT switches to "H", when the cell voltage is lower than over-charge detector threshold, or by disconnecting a charger. The output of Over-discharge detector or Excess discharge-current detector switches to "L" level after internally fixed delay time, when discharged voltage crosses the detector threshold from a high value to a value lower than V DET2. They have two types to release Over-discharge detector. The one is called "Latch type". The output of D OUT switches to "H" by connecting a charger to the battery pack when the battery supply voltage becomes higher than the over-discharge detector threshold. The other is called "Auto Release type", in case that the charger is not connected, when the cell voltage becomes equal released voltage from over-discharge detector is released. In case that a charger is connected, and when the cell voltage becomes higher than the over -discharge detector threshold, or becomes released voltage from over - discharge without connecting a charger, the over-discharge detector is released. Even if the battery is discharged to 0V, charge current is normally acceptable. However, KF version and KG version are 0V batteries unacceptable types. An excess discharge-current and short circuit state can be sensed and cut off through the built in excess current detector with D OUT being enabled to low level. Once after detecting excess discharge- current or short circuit is released and DOUT level switches to high by detaching a battery pack from a load system. After detecting over-discharge, supply current will be kept extremely low by halting internal circuits' operation. When the output of COUT is "H", if V- pin level is set at VSS−2V or lower, the delay time of detector can be shortened. Especially, the delay time of over-charge detector can be reduced into approximately 1/ 60. Therefore, testing time of protector circuit board can be reduced. Output type of COUT and DOUT are CMOS. The R5403x Series have SOT-23-5 and DFN(PL)1820-6. The R5405x Series have SOT-23-6 and DFN(PL)1616-6 and DFN1814-6. *R5403K (DFN(PL)1820-6) is the discontinued product as of March in 2020.

NO. EA-215-230201 OPERATION

• VD1 / Over-Charge Detector The VD1 monitors V DD pin voltage while charge the battery pack. When the V DD voltage crosses over -charge detector threshold VDET1 from a low value to a value higher than the V DET1, the VD1 can detect over-charge and an external charge control Nch MOSFET turn off with COUT pin being at "L" level. In terms of C, G version (Latch type), to reset the VD1 making the COUT pin level to "H" again after detecting over- charge, in such conditions that a time when the V DD voltage is down to a level lower than over -charge voltage, by disconnecting a charger from the battery pack. Output voltage of C OUT pin becomes "H", and it mak es an external Nch MOSFET turn on, and charge cycle is available. Depending on the external characteristics of external components such as FETs, just by disconnecting a charger, over-charge state may not be released. In such a case, by connecting some load, the over-charge state is released.) In other words, once over -charge is detected, even if the supply voltage becomes low enough, if a charger is continuously connected to the battery pack, recharge is not possible. Therefore this over -charge detector has no hysteresis. To judge whether or not load is connected, the built-in excess-discharge current detector is used. In other words, by connecting some load, V- pin voltage becomes equal or more than excess- discharge current detector threshold, and reset the over-charge detecting state. In terms of D, E, F version (Auto Release type), after detecting over -charge, if VDD pin voltage is equal or lower than the released voltage from over -charge, even if a charger is connected, over -charge detector is released. Further, in case that V DD pin level is lower than the over -charge detector threshold, if a charger is removed, over - charge detector is also released. Depending on the characteristics of external components such as FETs, just by disconnecting a charger, over-charge detector may not be released, and in this case, by connecting some load, the over-charge state is released. After detecting over-charge with the VDD voltage of higher than VDET1, connecting system load to the battery pack makes load current allowable through parasitic diode of external charge control FET. The COUT level would be "H" when the VDD level is down to a level below the VDET1 by continuous drawing of load current. Internal fixed output delay times for over -charge detection and release from over -charge exist. Even when the VDD pin level becomes equal or higher level than V DET1 if the VDD voltage would be back to a level lower than the VDET1 within a time period of the output delay time, VD1 would not output a signal for turning off the charge control FET. Besides, after detecting over -charge, while the V DD is lower than over -charge detector, even if a charger is removed and a load is connected, if the voltage is recovered within output delay time of release from over -charge, over-charge state is not released. A level shifter incorporated in a buffer driver for the COUT pin makes the "L" level of COUT pin to the V- pin voltage and the "H" level of COUT pin is set to VDD voltage with CMOS buffer.
• VD2 / Over-Discharge Detector The VD2 is monit oring a V DD pin voltage. When the V DD voltage crosses the over -discharge detector threshold VDET2 from a high value to a value lower than the V DET2, the VD2 can detect an over-discharge and the external discharge control Nch MOSFET turns off with the DOUT pin being at "L" level. In terms of C, E, G version(Latch type), to reset the VD2 with the D OUT pin level being "H" again after detecting over discharge, it is necessary to connect a charger to the battery pack. When the V DD voltage stays under over - discharge detector threshold VDET2, charge-current can flow through parasitic diode of an external discharge control MOSFET, then after the VDD voltage comes up to a value larger than VDET2, then, DOUT becomes "H" and discharging process would be able to advance through ON state MOSFET for discharge control. Connecting a charger to the battery pack makes the D OUT level being "H" instantaneously when the V DD voltage *R5403K (DFN(PL)1820-6) is the discontinued product as of March in 2020.

NO. EA-215-230201 is higher than VDET2. In terms of D, F version (Auto Release type), released operation by connecting a charger is same as the other latch type. However, without a charger, if V DD pin voltage is equal or more than the released voltage from over - discharge, DOUT pin becomes "H" immediately. When a cell voltage equals to zero, C, D, E version (acceptable type): if the voltage of a charger is equal or more than 0V-charge minimum voltage limit (Vst), COUT pin becomes "H" and a system is allowable to charge. F, G version (unacceptable type): if VDD voltage is less than charger inhibit maximum voltage (V nochg), even if a charger is connected, COUT level will be fixed at "L", and charge current will be cut off. An output delay time for over -discharge detection is fixed internally. When the V DD level is down to a equal or lower level than V DET2 if the VDD voltage would be back to a level higher than the V DET2 within a time period of the output delay time, VD2 would not output a signal for turning off the discharge control FET. Output delay time for release from over-discharge is also set. After detecting over-discharge by VD2, C, E, G version (Latch type): supply current would be reduced and be into standby by halting unnecessary circuits and consumption current of IC itself is made as small as possible. (Max. 0.1µA at VDD=2.0V) D, F version (Auto Release type): supply current would be reduced and be into standby by halting circuits except the over-discharge released by voltage function. (Max. 2.0µA at VDD=2.0V) The output type of DOUT pin is CMOS having "H" level of VDD and "L" level of VSS.

• VD3 /Excess discharge-current Detector, Short Circuit Protector Both of the excess current detector and short circuit protection can work when the both of control FETs are in "ON" state. When the V- pin voltage is up to a value between the short protection voltage (Vshort) /VDD and excess discharge- current threshold VDET3, VD3 operates and further soaring of V- pin voltage higher than Vshort (Typ. 0.8V) makes the short circuit protector enabled. This leads the external discharge control Nch MOSFET turns off with the D OUT pin being at "L" level. An output delay time for the excess discharge-current detector is internally fixed. A quick recovery of V- pin level from a value between Vshort and VDET3 within the delay time keeps the discharge control FET staying "H" state. Output delay time for Release from excess discharge-current detection is also set. When the short circuit protector is enabled, the DOUT would be "L" and the delay time (Typ. 1.2ms) is also set. The V- pin has a built -in pull-down resistor (Typ. 50kΩ) to the V SS pin, that is, the resistance to release from excess-discharge current. After an excess discharge-current or short circuit protection is detected, removing a cause of excess discharge- current or external short circuit makes an external discharge control FET to an "ON" state automatically with the V- pin level being down to the V SS level through built-in pulled down resistor. The reset resistor of excess discharge- current is off at normal state. Only when detecting excess discharge-current or short circuit, the resistor is on. Output delay time of excess discharge- current is set shorter than the delay time for over -discharge detector. Therefore, if VDD voltage would be lower than V DET2 at the same time as the excess discharge- current is detected, the R5403x /R5405x are at excess discharge-current detection mode. By disconnecting a load, VD3 is automatically released from excess discharge-current.
• VD4 /Excess charge-current detector When the battery pack is chargeable and discharge is also possible, VD4 senses V- pin voltage. For example, in case that a battery pack is charged by an inappropriate charger, an excess current flows, then the voltage of V- pin becomes equal or less than excess charge- current detector threshold. Then, the output of C OUT becomes "L", and prevents from flowing excess current in the circuit by turning off the external Nch MOSFET. Output delay of excess charge current is internally fixed. Even the voltage level of V- pin becomes equal or lower than the excess charge-current detector threshold, the voltage is higher than the VD4 threshold within the delay *R5403K (DFN(PL)1820-6) is the discontinued product as of March in 2020.

NO. EA-215-230201 time, the excess charge current is not detected. Output delay for the release from excess charge current (Typ. 1.2ms) is also set. VD4 can be released with disconnecting a charger and connecting a load.

• DS (Delay Shorten) function Output delay time of over -charge, over-discharge, and release from those detecting modes can be shorter than those setting value by forcing equal or less than the delay shortening mode voltage (Typ. −2.0V) to V- pin. *R5403K (DFN(PL)1820-6) is the discontinued product as of March in 2020.

NO. EA-215-230201 TYPICAL APPLICATION VDD COUT DOUT VSS 0.01µF 1kΩ 330Ω R5403/R5405 APPLICATION HINTS R1 an d C1 will stabilize a supply voltage to the R5403x /R5405x. A recommended R1 value is less than 1kΩ. A larger value of R1 leads higher detection voltage, makes some errors because of some conduction current may flow in the R5403x /R5405x. Further, to stabilize the operation of the R5405, use the C1 with the value in the range from 0.001uF to 0.01uF. To choose the most suitable value of C1, fully evaluation is necessary. R1 and R2 can operate also as parts for current limit circuit against reverse charge or applying a charger with excess charging voltage to the R5403x /R5405x, battery pack. Small value of R1 and R2 may cause over -power consumption rating of power dissipation of the R5403x /R5405x. Thus, the total value of R1+R2 should be equal or more than 1kΩ. On the other hand, if large value of R2 is set, release from over-discharge by connecting a charger might not be possible. Recommended R2 value is equal or less than 10kΩ. The application circuit's performance is largely dependable on the actual PCB layout, therefore, fully evaluation and s election of the appropriate external components are necessary.
