3 Description

The BQ34Z100-R2 device is an Impedance Track?

fuel gauge for Li-ion, PbA, NiMH, and NiCd

batteries, and works independently of battery seriescell

configurations. Batteries from 3 V to 16.7 KV

can be easily supported through an external voltage

translation circuit that is controlled automatically to

reduce system power consumption.

The BQ34Z100-R2 device provides several interface

options, including an I2C peripheral, an HDQ

peripheral, one or four direct LEDs, and an ALERT

output pin. Additionally, the BQ34Z100-R2 provides

support for an external port expander for more than

four LEDs.
