The BQ771823DPJR from Texas Instruments is a dedicated overvoltage protection IC for lithium-ion battery pack systems. It independently monitors each cell for overvoltage conditions, ensuring system safety and longevity. This device supports battery configurations from 2-series up to 5-series cells.
Key features include high-accuracy overvoltage protection with a tolerance of ±10 mV and a fixed OVP threshold. It also boasts very low power consumption, drawing approximately 1 µA when below the protection voltage, and a low leakage current per cell input of less than 100 nA. An internal delay timer is incorporated, which initiates upon detection of an overvoltage condition. Upon expiration of this timer, the output is triggered into its active state.
Designed for reliability, the BQ771823DPJR is functional safety-capable, with documentation available to aid in system design. It is available in a small 8-pin WSON package with exposed pad, suitable for surface mounting. This makes it ideal for applications requiring compact battery management solutions.
Typical applications include protection for battery packs used in handheld garden tools, handheld power tools, cordless vacuum cleaners, UPS battery backup systems, and light electric vehicles such as eBikes and eScooters.
