BQ76PL536ATPAPRQ1 Description

Short technical summary and product information.

The BQ76PL536ATPAPRQ1 from Texas Instruments is an integrated circuit designed for battery monitoring and secondary protection in automotive battery packs, particularly for EV and HEV applications. This device supports 3 to 6 series Lithium-Ion cells, accommodating all chemistries.

 

Key electrical features include a supply voltage range from 7.2 V to 27 V with a peak of 36 V, and a high-speed SPI communication interface for data transfer. It offers precise battery monitoring with a typical ADC accuracy of ±1 mV and 14-bit resolution, converting in 6 µs. The IC includes built-in comparators for overvoltage, undervoltage, and overtemperature protection with programmable thresholds and delay times. It also provides cell balancing control outputs.

 

Designed for automotive applications, the BQ76PL536ATPAPRQ1 is AEC-Q100 qualified with a temperature grade of 2, allowing operation from -40°C to 105°C. It is housed in a 64-HTQFP package measuring 10 mm × 12 mm and is suitable for surface mount applications. The device also features a low operating current, with typical values of 12 µA in sleep mode and 45 µA in idle mode, and includes an integrated 5-V, 3-mA LDO.
