- Fixed programmable delay timer
- Fixed OVP threshold - Available range from 3.85 V to 4.6 V
- Fixed OVP delay option: 4 s or 6.5 s
- High-accuracy overvoltage protection: ±10 mV
- Low power consumption ICC ≈ 1 µA (VCELL(ALL) < VPROTECT)
- Low leakage current per cell input < 100 nA
- Small package footprint - 6-pin SON
