BQ29440DRBT More Information

BQ2944x Secondary Overvoltage Protection ICs: The OMO Electronic bq2944x is a secondary overvoltage protection IC for 2-series, 3-series, or 4-series cell lithium-ion battery packs. The TI bq2944x incorporates a high-accuracy precision overvoltage detection circuit. This TI secondary overvoltage protection IC compares the voltage of each cell in a battery pack to an internal reference voltage. If any cells reach an overvoltage condition, the TI bq2944x starts a timer that provides a delay proportional to the capacitance on the CD pin. Upon expiration of the internal timer, the OUT pin changes from a low state to a high state. An optional latch configuration is available that holds the OUT pin in a high state indefinitely after an overvoltage condition has satisfied the specified delay timer period. The latch is released when the CD pin is shorted to GND. This TI secondary overvoltage protection IC is designed for Li-Ion battery packs in notebook computers, power tools, and portable equipment and instrumentation.
