BQ76PL536PAPT

Product Summary

The BQ76PL536PAPT is a stackable three to six series cell lithium-ion battery pack protector and analog front end (AFE) that incorporates a precision analog-to-digital converter (ADC); independent cell voltage and temperature protection; cell balancing, and a precision 5-V regulator to power user circuitry. The BQ76PL536PAPT integrates a voltage translation and precision analog-to-digital converter system to measure battery cell voltages with high accuracy and speed. The applications of the BQ76PL536PAPT include Uninterruptible Power Systems (UPS), E-Bike and E-Scooter, Large-Format Battery Systems, Electric and Hybrid Electric Vehicles.
