Features
2-series, 3-series, and 4-series
cell overvoltage protection (OVP)
Factory programmed OVP threshold (3.6V to 5.2V) with ±12mV accuracy
Fixed delay timer to trigger FET drive output
(0.25s to 6.5s options)
Output pin options:
Active high
Open-drain - active pulldown
Open-drain - inactive pulldown
Integrated 3mA regulated output programmable to 3.8V, 3.3V, 3.15V, 3.0V, 2.5V, 1.8V, or 1.5V
Factory programmed undervoltage (UV) detection threshold (1V to 4.15V) to disable regulator
OVP remains operational even in undervoltage condition
Multiple power modes:
NORMAL mode - no OV or UV: I
CC
≅ 1.23µA
Undervoltage mode - UV detected: I
CC
≅ 0.25µA
Overvoltage mode - OV detected: I
CC
≅ 19µA
Low leakage current per cell input < 100nA
Small package footprint
8-Pin WSON (2mm × 2mm)
