RT9941 Description

RT9941 Power Management ICs for Handheld Device General .
The RT9941 is a complete power management IC (PMIC) for handheld device platform.

RT9941 Features

* z Charger Adapter & Battery Two Input with Auto Power Dynamic Path. ` PWR_IN LDO support continuous 1.5A, peak 2A current ` 4.5V to 5.5V Operation Voltage Range with Max. Input 18V from PWR_IN Pin ` Switch Well for LDO and Charger Power MOSFET ` Set Charge Current by ISETA Pin ` Charge Status Indic

RT9941 Applications

* They utilize a proprietary hysteretic PWM control scheme that switches with nearly fixed frequency and is adjustable, allowing the customer to trade some efficiency for smaller external component as desired. The LDO linear regulators provide high power supply rejection rate and have only 45μVRMS of
