RT9750
6-A Smart Load Switch Battery Charger
General Description
The RT9750 is a 6-A smart load switch battery charger,
which integrates an internal load switch with charge pump
control and 4-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.
