RT9750

6A Smart Load Switch Battery Charger

The RT9750 is a 6A smart load switch battery charger, which integrates an internal load switch with charge pump control and 3-path constant current/constant voltage regulation, a 5-way hardware protection, and a 8-Channel 12-bit analog-to-digital converter. The RT9750 provides the accurate analog-to-digital converter for voltage/current measurement by I²C serial interface to report the battery charging parameters and 3-way software protection and flags.
