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 (non-removable) or a removable battery
pack.

Switchmode Charger, the bq27530-G1 manages an embedded battery (non-removable) 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 (%), run-time to empty (min), battery voltage (mV),
temperature (°C) and state of health (%).

Battery fuel gauging with the bq27530-G1 requires only PACK+ (P+), PACK– (P–), and Thermistor (T)
connections to a removable battery pack or embedded battery circuit. The CSP option is a 15-ball package in the
dimensions of 2,61 mm × 1,96 mm with 0,5 mm lead pitch. It is ideal for space constrained applications.
