3 Description

The Texas Instruments bq27530-G1 system-side Li-

Ion Battery Management Unit is a microcontroller

peripheral that provides Impedance Track™ fuel

gauging and charging control for single-cell Li-Ion

battery packs. The device requires little system

microcontroller firmware development. Together with

bq2416x Single-Cell Switchmode Charger, the

bq27530-G1 manages an embedded battery (nonremovable)

or a removable battery pack.

The bq27530-G1 uses the patented Impedance

Track™ algorithm for fuel gauging, and provides

information such as remaining battery capacity

(mAh), state-of-charge (%), runtime-to-empty (min),

battery voltage (mV), temperature (°C), and state-ofhealth

(%).
