NO.EA-349-250909 THEORY OF OPERATION Overcharge Detection Circuit, VD1-n (n = 1, 2, 3, 4) While the cells are charged, the voltage between V C1 pin and VC2 pin (Cell-1 voltage), the voltage between VC2 pin and VC3 pin (Cell-2 voltage), and the voltage between VC3 pin and VC4 pin (Cell-3 voltage), and the voltage between V C4 pin and V SS pin (Cell-4 voltage) are supervised. If at least one of the cells’ voltage becomes equal or more than the over-charge detector threshold, the over-charge is detected, and an external charge control Nch. FET turns on with COUT pin being at "H" level and by cutting a fuse on the charger path, and charge stops. To reset the over -charge and make the COUT pin level to "L" again after detecting over -charge, in such conditions that a time when all the cells’ voltages are down to a level lower than over-charge released voltage. Internal fixed output delay times for over -charge detection and release from over -charge exist. Even if one of voltage of the cells keeps its level more than the over-charge detector threshold, and output delay time passes, over-charge voltage is detected. In the case of Timer Reset Delay available version, if all the cell voltages become lower than the over-charge detector threshold within the output delay time of over-charge detector by noise or other reasons, the time period is less than over -charge detector timer reset output delay time, the over-charge delay time is accumulated and maintained, and the accumulated delay time reaches the output delay time of over-charge, the over-charge is detected. After detecting over-charge, even if all the cell voltages become equal or less than the released voltage from over-charge, if at least one of the cells voltage becomes higher than the released voltage from over-charge within the output delay time of the release from over-charge, then over-charge is not released. The output type of the COUT pin is CMOS output between V SS and the built -in regulator, and "H" level of COUT pin is the output voltage of the built-in regulator.

NO.EA-349-250909 Technical Notes on Selection Component

  • The voltage fluctuation is stabilized with R VDD and C VDD. If a small R VDD is set, in the case of the large transient may happen to the cell voltage, by the flowing current, the IC may be unstable. If a large R VDD is set, by the consumption current of the IC itself, the voltage difference between V DD pin and V C1 pin is generated, and unexpected operation may result. Therefore, the appropriate value range of R VDD is from 100 Ω to 1 kΩ. The built-in voltage regulator (VR) is designed as a power source for an RTC. If the VR is used for other purpose, RVDD value should be set so that VDD does not become smaller than VC1- 0.3V by RVDD and a load current. If VDD value is smaller than VC1-0.3V, the overvoltage detection voltage might shift or unexpected operation might result. To make a stable operation of the IC, the appropriate value range of CVDD is from 0.01 µF to 1.0 µF.
  • The voltage fluctuation is stabilized with R1 to R4 and C1 to C4. If a R1 to R4 is too large, by the conduction current at detection, the detector threshold may shift higher. Therefore, the appropriate value range of R1 to R4 is equal or less than 1 kΩ. To make a stable operation of the IC, the appropriate value range of C1 to C4 is 0.01 µF or more.
  • The typical application circuit diagrams are just examples. This circuit performance largely depends on the PCB layout and external components. In the actual application, fully evaluation is necessary.
  • Over-voltage and the over current beyond the absolute maximum rating should not be forced to the protection IC and external components. During the time until the fuse is open after detecting over -charge, a large current may flow through the FET. Select an FET with large enough current capacity in order to endure the large current.
  • Our company cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in our products. If technical notes are not complied with the circuit which is used our products, we are not responsible for any damages and any accidents.
  • To connect the SC protector, connect the SC protector to the cell must be the last. Contact Information for Inquiries regarding SC PROTECTOR Dexerials Corporation (Sony Chemical & Information Device Company Ltd.) URL: http://www.dexerials.jp

NO.EA-349-250909 TECHNICAL NOTES A peripheral component or the device mounted on PCB should not exceed a rated voltage, a rated current or a rated power. When designing a peripheral circuit, please be fully aware of the following points.

  • Please evaluate the product at the PCB level before use, as some symptoms may remain that cannot be confirmed by the evaluation at the IC level.
  • When using any coating or underfill to improve moisture resistance or joining strength, evaluate them adequately before using. In certain materials or coating conditions, corrosion by contained constituents, current leakage by moisture absorption, crack and delamination by physical stress can happen. If the curing temperature of the coating material or underfill material exceeds the absolute maximum rating, the electrical characteristics of this product may change.
  • When performing X -ray inspection in mass production process and evaluation build stage such as the product functions and characteristics confirmation, please confirm X-ray irradiation does not exceed 1.5Gy (absorbed dose for air).
