Release Information

Overview

BQ34Z100-DEVICE-FW is a firmware-only release that can be flashed onto any existing BQ34Z100 hardware ( such as the BQ34Z100, BQ34Z100-R1, BQ34Z100-R2, … device ). The firmware incorporates the patented Impedance Track™ technology to create a pack-based solution for Li-ion, PbA, NiMH, and NiCd batteries, and works independently of battery series-cell 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-DEVICE-FW 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-DEVICE-FW provides support for an external port expander for more than four LEDs.

Features

The BQ34Z100-DEVICE-FW firmware is usable on any previous version of the BQ34Z100 hardware
