Description
The bq296xxx family is a high accuracy, low power overvoltage protector with a 1-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. The regulated output supply delivers up to 1-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.
