BQ7695202PFBR battery monitor and protector
The BQ7695202PFBR is a high-accuracy, highly integrated battery monitor and protector from Texas Instruments, designed for 3-series to 16-series Li-ion, Li-polymer, and LiFePO4 battery packs. Housed in a 48-pin TQFP package, it operates from -40°C to +85°C and supports a wide battery voltage range up to 80V, with 85V tolerance on cell connection pins for robust handling during production and operation. It integrates dual independent ADCs, high-side charge-pump NFET drivers, dual programmable LDOs, and multi-interface communication (I2C, SPI, HDQ), serving as a compact, all-in-one solution for industrial, automotive, and energy storage battery management systems.
BQ7695202PFBR Key Features Applications
It delivers industry-leading monitoring accuracy with typical cell voltage measurement error under 10mV and coulomb counter offset error below 1µV, enabling precise state-of-charge tracking. The comprehensive protection suite includes overvoltage, undervoltage, overcurrent, short-circuit, and overtemperature protection, plus secondary chemical fuse drive and open-wire detection for fail-safe operation. It supports both autonomous and host-controlled cell balancing, alongside multiple power modes: normal (286µA), sleep (24–41µA), deep sleep (9–10µA), and shutdown (1µA), minimizing power consumption in battery-powered systems. Communication options include 400kHz I2C, SPI, and HDQ, while integrated OTP memory allows customer programming during production.
This chip is ideal for high-capacity battery packs in energy storage systems (ESS), electric forklifts, and industrial drones, leveraging its 3–16 cell support and high-voltage tolerance. It serves automotive applications such as electric two-wheelers and auxiliary battery systems, providing reliable protection and monitoring for lithium-based batteries. Additionally, it is used in medical equipment, portable power stations, and telecom backup power, where high accuracy, low power, and robust fault protection are critical for battery safety and longevity.
