BQ296xxx Overvoltage Protection for 2-Series, 3-Series, and 4-Series Cell  
Li-Ion Batteries with Regulated Output Supply  
1 Features  
3 Description  
2-series, 3-series, and 4-series cell overvoltage  
protection (OVP)  
Fixed delay timer to trigger FET drive output  
(3-s, 4-s, 5.5-s, or 6.5-s options)  
Factory programmed OVP threshold (threshold  
range 3.85 V to 4.6 V)  
Output options: active high  
High-accuracy overvoltage protection:  
±10 mV  
The BQ296xxx family is a high-accuracy, low-power  
overvoltage protector with a 2-mA regulated output  
supply for Li-ion battery pack applications.  
Each cell in a 2-series to 4-series cell stack is  
individually monitored for an overvoltage condition. An  
internally fixed-delay timer is initiated upon detection  
of an overvoltage condition on any cell. Upon  
expiration of the delay timer, an output pin is triggered  
into an active state to indicate that an overvoltage  
condition has occurred.  
Regulated supply output with self-disable and/or  
external enable/disable control  
The regulated output supply delivers up to 2-mA  
(max) output current to drive always-on circuits, such  
as a real-time clock (RTC) oscillator. The BQ296xxx  
family has a self-disable function to turn off the  
regulated output if any cell voltage falls below a  
certain threshold, thereby preventing drain on the  
battery, and provides an external control to enable or  
disable the regulated output.  
– Options: 3.3 V, 2.5 V, and 1.8 V (BQ2961)  
– Options: 3.3 V, 3.15 V, 3.0 V (BQ2962)  
Low power consumption ICC ~ 4 µA  
(VCELL(ALL) < VPROTECT  
)
Extra low power consumption with reg output  
disabled, ICC ~ 1.2 µA  
Low leakage current per cell input < 100 nA  
Small package footprint  
– 8-Pin WSON (2 mm × 2 mm)
