Battery charger IC cuts charge time by 60%

It uses proprietary MaxCharge technology that reduces charge time up to 60% compared to existing battery chargers, says the company. The switch-mode charger offers faster charge times and cooler charging to extend the overall life of electronics in many Li-ion applications, including smartphones, tablets, drones, power banks, and industrial and medical equipment.

The charger, which charges at 3.5A with minimal 18˚C temperature rise, combines narrow-voltage DC/DC power path management with MaxCharge, to support input voltages up to 14V while providing charge current up to 5A. 

It provides up to 91% charging efficiency at 9Vin 3.5A with only an 18˚C temperature rise. Excess heat is reduced by controlling the IC temperature and optimise thermal performance with a thermal-regulation loop. It is pin-to-pin compatible with the company’s bq24192 family.

The I2C-controlled 1S, 5A fast charger is featured in a new reference design, TIDA-00538, using MaxCharge for high input voltage and adjustable USB OTG boost, which enables turn-key access to reduce battery-charging time and improve battery run time during the discharging phase.
