BATTERY PROTECTION IC
FOR 3-SERIES CELL PACK
Rev.1.0_00
The S-8203A Series includes high-accuracy voltage detection circuits and delay circuits, in single use, makes it possible for
users to monitor the status of 3-series cell lithium-ion rechargeable battery.
The S-8203A Series is suitable for protecting lithium-ion rechargeable battery pack from overcharge, overdischarge, and
overcurrent.

*1. The overcharge detection voltage n (n = 1 to 3) and overdischarge detection voltage (n = 1 to 3) cannot be selected if
the voltage difference between them is 0.6 V or lower.
*2. Overcharge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV step.
(Overcharge hysteresis voltage = Overcharge detection voltage − Overcharge release voltage)
*3. Overdischarge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.2 V to 0.7 V in 100 mV
step.
(Overdischarge hysteresis voltage = Overdischarge release voltage − Overdischarge detection voltage)
*4. The discharge overcurrent detection voltage and load short-circuiting detection voltage cannot be selected if the
voltage difference between them is 0.3 V or lower.
 Application
