The S-8254A series is a protection IC for 3-serial or 4-serial cell lithium ion rechargeable batteries and includes a high-accuracy voltage detector and delay circuit.
The S-8254 series protects both 3-serial or 4-serial cells using the SEL pin for switching.

Features

High-accuracy voltage detection for each cell
Overcharge detection voltage n(n=1 to 4): 3.90 V to 4.45 V (50 mV steps) Accuracy ±25 mV
Overcharge release voltage n(n=1 to 4): 3.80 V to 4.45 V Accuracy ±50 mV
Overdischarge detection voltage n(n =1 to 4): 2.0 V to 3.0 V (100 mV steps) Accuracy ±80mV
Overdischarge release voltage n(n=1 to 4): 2.0 V to 3.4 V Accuracy ±100 mV
Three-level overcurrent protection
Overcurrent detection voltage 1: 0.05 V to 0.3 V (50 mV steps) Accuracy ±25 mV
Overcurrent detection voltage 2: 0.5 V Accuracy ±100 mV
Overcurrent detection voltage 3: VVC1 – 1.2 V Accuracy ±300 mV
Delay times for overcharge detection, overdischarge detection and overcurrent detection 1 can be set by external capacitors. (Delay times for overcurrent detection 2 and 3 are fixed internally.)
Switchable between a 3-serial cell and 4-serial cell using the SEL pin
Charge/discharge operation can be controlled via the control pins.
