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 I_CC~ 4 µA

(V_CELL(ALL)< V_PROTECT

)

Extra low power consumption with reg output

disabled, I_CC~ 1.2 µA

Low leakage current per cell input < 100 nA

Small package footprint
