TIBQ76952PFBR

Overview

The BQ76952PFBR is a high-accuracy battery monitor and protector designed for 3-series to 16-series Li-ion, LiFePO4, and LTO battery packs. It features an integrated charge pump for high-side NFET protection, two independent ADCs for simultaneous current and voltage sampling, and a wide 85 V high-voltage tolerance. The device supports both autonomous operation and host-controlled management via I2C or SPI interfaces.

Why Choose This Part

This controller offers extreme precision with 0.5 percent accuracy and simultaneous sampling to eliminate synchronization errors in power calculations. Its integrated high-side NFET driver and charge pump simplify system design by removing the need for external drivers. Furthermore, the low 286 uA operating current and 1 uA shutdown mode significantly extend shelf life for stored battery packs.

Applications

Getting Started

Start development using the BQ76952EVM evaluation module, which interfaces with a PC via the USB-to-GPIO adapter. Texas Instruments provides the Battery Management Studio (BQSTUDIO) software for configuring the integrated OTP memory and monitoring real-time data. Engineers should review the random cell attach sequence guidelines to leverage the device's robust assembly tolerance.
