Texas Instruments BQ24650RVAT, Battery Charge Controller IC, 5 to 28 V 16-Pin, VQFN

The bq24650 provides input voltage regulation, which reduces charge current when input voltage falls below a programmed level. The Charge Controller offers a constant-frequency synchronous PWM controller with high accuracy current and voltage regulation, charge pre-conditioning, charge termination, and charge status monitoring.
