BQ771817DPJR Description

Short technical summary and product information.

The BQ771817DPJR from Texas Instruments is an integrated circuit designed for battery protection in Li-Ion systems. It monitors each cell independently for overvoltage conditions and features an internal delay timer that triggers the output upon expiration. This device supports 2 to 5-series cell configurations.

Key electrical specifications include high-accuracy overvoltage protection with a tolerance of ±10 mV, very low power consumption of approximately 1 µA when below the protection threshold, and low leakage current per cell input of less than 100 nA. It also includes a Customer Test Mode (CTM) for faster production-line testing.

The BQ771817DPJR is housed in a compact 8-WSON (3x4 mm) surface-mount package, making it suitable for space-constrained applications. The operating temperature range is -40°C to 85°C. This IC is functional safety-capable, with documentation available to aid in system design.

This battery protector is ideal for applications requiring reliable overvoltage monitoring and protection in portable electronics, power tools, and energy storage systems.
