BQ7695204PFBR

The Texas Instruments BQ76952 device is a
highly integrated, high-accuracy battery monitor
and protector for 3-series to 16-series Li-ion, Lipolymer, and LiFePO4 battery 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 BQ76952 device is available in a 48-pin TQFP
package.
