Description
General part information
BQ27532-G1 Series
The bq27532-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 fuel gauge requires little system microcontroller firmware development. Together with bq2425x single-cell switch-mode charger, the fuel gauge manages an embedded battery (non-removable) or a removable battery pack.
The fuel gauge uses the patented Impedance Track algorithm for fuel gauging, and provides information, such as remaining battery capacity (mAh), state-of-charge (%), runtime-to-empty (minimum), battery voltage (mV), temperature (°C), and SoH (%).
Battery fuel gauging with the device requires only PACK+ (P+), PACK– (P–), and thermistor (T) connections to a removable battery pack or embedded battery circuit. The 15-pin NanoFree™ (CSP) package has dimensions of 2.61 mm × 1.96 mm with 0.5-mm lead pitch. It is ideal for space-constrained applications.
