BQ77905 Datasheet Stackable Lithium-ion Battery Protector

Manufacturer: Texas Instruments

Overview: BQ77904, BQ77905 SLUSCM3K – JUNE 2016 – REVISED JULY 2020 BQ77904, BQ77905 3-Series to 20-Series Ultra Low-Power Voltage, Current, Temperature, and Open-Wire Stackable Lithium-Ion Battery Protector.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The BQ77904 and BQ77905 devices are low-power battery pack protectors that implement a suite of voltage, current, and temperature protections without microcontroller (MCU) control.

The device's stackable interface provides simple scaling to support battery cell applications from 3 series to 20 series or more.

Protection thresholds and delays are factory-programmed and available in a variety of configurations.
