Description

General part information

BQ7694202 Series

The Texas Instruments BQ76942 is a highly integrated, high accuracy battery monitor and protector for 3-series to 10-series Li-ion, Li-polymer, and LiFePO‌‌‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍4battery packs. The device includes a high-accuracy monitoring system, a highly configurable protection subsystem, and support for autonomous or host-controlled cell balancing. Integration includes high-side charge-pump NFET drivers, dual programmable LDOs for external system use, and a host communication peripheral supporting 400-kHz I2C, SPI, and HDQ one-wire standards. The BQ76942 is available in a 48-pin TQFP package.
