Li-ion battery charger

10 June 2015 Power Electronics / Power Management

Texas Instruments introduced a single-cell lithium-ion (Li-ion) battery charger circuit with proprietary MaxCharge technology that it claims reduces charge time by up to 60% compared to existing battery chargers. The bq25892 switch-mode charger, which charges at 3,5 A with minimal 18°C temperature rise, utilises narrow-voltage DC-DC power path management to support input voltages up to 14 V while providing charge current up to 5 A. The IC is designed to work in single-cell portable devices with TI battery fuel gauges.
