BQ771815DPJR Description

Short technical summary and product information.

The BQ771815DPJR from Texas Instruments is a battery protector IC specifically designed for 2 to 5 series Li-Ion battery packs. It provides essential overvoltage protection, monitoring each cell independently to prevent damage from overcharging.

 

Key electrical specifications include a maximum input voltage of 25V and a typical operating current of just 1µA, making it suitable for low-power applications. The overvoltage protection thresholds range from a minimum of 3.85V to a maximum of 4.65V per cell, ensuring reliable operation within safe limits.

 

This IC operates across a wide temperature range of -40°C to 110°C, accommodating various environmental conditions. It is supplied in an 8-WSON (3x4) surface-mount package, offering a compact solution for battery management systems. The device is also noted for its high-accuracy overvoltage protection with a tolerance of ±10 mV and low leakage current per cell input of less than 100 nA.

 

The BQ771815DPJR is functional safety-capable, with documentation available to aid in the design of safety-critical systems. Its design includes an internal delay timer that triggers the output upon detection of an overvoltage condition, and it supports stackable configurations for greater flexibility.
