Page 8 of 14Rev.1.0 May 7 ,2013 R03DS0071EJ0100 Operational Description Adaptor detection Adaptor connection is detected. VCC>3.8V : Adapter connection is detected to be connected. (charge permission) VCC<2.5V : Adapter connection is detected to be disconnected. (mode is reset and returns to start.) Each detecting operation during adaptor detection is as follows. - Battery connection/disconnection : count valid (continues to detect without suspending.) - Quick charge start voltage detection : count suspended - Charge completion current/voltage detection : count suspended - Recharge start voltage detection : count suspended - Chip temperature detection : count reset (When adaptor is detected in quick charge mode, IC starts to charge at 0.2C.(VCC>Vadp)) During below charge Off time, IC continues to count even if the adaptor is detected. - Forced charge Off time after forced charge completed. - Charge Off time from quick charge to charge completion. - Charge Off time from charge completion to quick charge. When adaptor is detected in forced charge mode, forced charge mode is reset and it is restarted after released adaptor detection. Battery connect detection When adapter is detected, forced charge (0.3C) is started for canceling the cutoff state of battery due to overdischarge protection. Then, forced charge is stopped and battery connection is detected. Battery connection detection has a hysteresis characteristic and the battery disconnection judgment voltage after battery connection detection is battery connection detection voltage -100mV. 1) Battery connect detection - Battery voltage(BAT)>1.1V : Battery connection is detected to be connected, and charge is started. - Battery voltage(BAT)<1.1V : Battery connection is detected to be disconnected (overdischarge protection) ,and charge stops. 2) Battery disconnect detection (under charge) - When the battery is disconnected under charge, the state shifts to CV control mode (charge current does not flow). Therefore, the state shifts to charge completion judgment mode. In this time, built-in charge transistor is to be OFF, and BAT terminal voltage falls. When BAT terminal < 1.0V, battery connection is detected to be disconnected, and charge stops. ,and the state shifts to battery non-connection mode. (overdischarge protection) 3) Battery disconnect detection (when charge is stopped) - In this condition, when the battery connection is detected to be disconnected, BAT terminal voltage falls. because built-in charge transistor is already OFF. When BAT terminal < 1.0V, battery connection is detected to be disconnected ,and the state shifts to battery non-connection mode. (overdischarge protection) Trickle charge (0.1C constant current charge) After adaptor connection judgment and battery connection judgment, trickle charge is started when battery voltage is as follows. 1.1V<battery voltage<3.0V During the trickle charge mode, VSENSE terminal is discharged by 300uA current. - When battery voltage > 3.0V, the state shifts to quick charge mode. - Trickle charge timer operates simultaneously with trickle charge start. - After trickle charge timer expires, when battery voltage < 3.0V, the state shifts to charge error mode. - When adaptor voltage is battery voltage or less, charge stops. - When battery voltage >4.35V(overvoltage), the state shifts to charge error mode.
Page 9 of 14Rev.1.0 May 7 ,2013 R03DS0071EJ0100 Quick charge (1.0C constant current charge) Quick charge is started when battery voltage > 3.0V. During the quick charge mode, VSENSE terminal is discharged by 300uA current. - When battery voltage is detected to be 4.2V, the state shifts to CV charge mode. - Quick charge timer operates simultaneously with quick charge start. - After quick charge timer expires, when the state is not in charge completion mode , it shifts to a charge error mode. - When battery voltage is detected to be less than 2.92V, the state shifts to trickle charge mode. - When adaptor voltage is detected to be battery voltage or less, charge stops. - When battery voltage is detected to be 4.35V or more, the state shifts to charge error mode. During quick charge, junction temperature is monitored to limit charge current value between 0.2C-1.0C so that the junction temperature may not exceed Ttreg. Charge current 1.0C = [ Reference voltage(1.495V) / RICHG ] x (820~920) * (mA) * The coefficient changes by the charging current. Constant voltage charge When battery voltage is detected to be 4.2V under quick charge, constant voltage charge of 4.2V is started. - If the charge current falls to charge completion current or less under constant voltage charge, the state shifts to charge completion judgment mode. - When 3.0V < battery voltage < 4.2V is detected, the state shifts to quick charge mode. - When adapter voltage is detected to be battery voltage or less, charge stops. - When battery voltage is detected to be 4.35V or more(overvoltage), the state shifts to charge error mode.

Page 10 of 14Rev.1.0 May 7 ,2013 R03DS0071EJ0100 Charge completion judgment mode When battery voltage >3.0V and charge current < charge completion current , the state shifts to charge completion judgment mode. During charge completion judgment mode, charge transistor is turned off and battery voltage is monitored. Battery voltage after charge transistor is OFF : - When battery voltage>2.92V, charge completes. - When 1.1V<battery voltage <2.92V, the state shifts to charge error mode. - When battery voltage < 1.1V, charge stops by battery disconnect detection. And when the state shifts to charge completion mode, quick charge timer is reset. Recharge function After charge completion, battery voltage continues to be monitored. When battery voltage < 3.97V, recharge is started. Quick charge timer also operates simultaneously with recharge start. Battery temperature detection function Battery temperature is detected by TH terminal voltage. - Low temperature side: Charge stops when battery temperature(falling) is worth 2 degC. Charge restarts when battery temperature(rising) is worth 4 degC. - High temperature side: Charge stops when battery temperature(rising) is worth 43 degC. Charge restarts when battery temperature(falling) is worth 38 degC. During charge stops, LED becomes OFF.(Timer is suspended during charge) After charge restarts, the state return to the state before it stopped. Timer ON/OFF control function When “H” signal is input to TMRcnt terminal, timer can be suspended forcefully. Even under charge, when “H” signal is input to TMRcnt terminal, timer is stopped and reset. When TMRcnt terminal is "L" or "open", timer is enabled and timer operation is started. Charge error mode The state shifts to charge error mode and charge stops, when conditions are as follows, - Overvoltage detection - Thermal shutdown detection - After trickle charge timer or quick charge timer expires. - When 1.1V < battery voltage < 2.92V is detected. (while battery voltage is monitored in charge completion judgment mode. ) When the following conditions are detected, charge error mode is canceled. - When battery voltage is detected to be less than 1.0V(battery is judged to be disconnected.) - When battery voltage is detected to be 2.5V or less.(power-on reset) While charge error mode, the battery discharge current is 10uA. Thermal shutdown When junction temperature becomes 140degC under charge, the state shifts to charge error mode.
