【文字介紹】

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.
held wireless devices. The RT9020 consumes typical 0.7μA in shutdown mode and has fast turn-on time less than 70μs (without C SS ).
The other features include ultra-low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Tiny packages SOT-23-5 and SC-70-5 are available.
