Product Descriptions
The Texas Instruments bq27531-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 bq2419x Single Cell Switchmode Charger, the bq27531-G1 manages an embedded battery (non-removable) or a removable battery pack.
The bq27531-G1 uses the patented Impedance Track™ algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (percent), run-time to empty (min), battery voltage (mV), temperature (°C) and state of health ( percent).
Battery fuel gauging with the bq27531-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.
