General Description

The RT9758 is a high efficiency and high charge current

charger for high voltage application. The efficiency is up

to 98.1 when VOUT = 10V, IOUT = 2A, switching

frequency = 500kHz, dual phase with VBUS input in cap

divider mode. The RT9758 maximum charge current is

up to 5A. The device integrates cap divider topology

(DIV2 mode), direct charge topology (Bypass mode), an

input reverse blocking NFET, a dual-phase charge

pump core, the EN pin control and 9-way protection. In

present mode (EN = H), the host can still order the

command by I2C serial interface.

Features

? Integrated Bidirectional Bypass Mode and Cap

Divider Mode (DIV2 Mode)

? Input Reverse Blocking NFET between WRX_IN

Pin and VBUS Pin

? 5A Output Current Capability

? Efficiency Up to 98.1 when VOUT = 10V, IOUT

= 2A, Switching Frequency = 500kHz and Dual

Phase with VBUS Input in DIV2 Mode

? 300kHz to 1.5MHz Variable Switching

Frequency Stay Out of Audio Band

? Spread Spectrum Technology for EMI

Reduction

? Adjustable Single-Phase or Dual-Phase for

DIV2 Mode

? Programmable Pre-Charge Current and Pre-

Charge Timing for Charge Soft-Start

? Support Converter Soft-Start with 200mA

Loading

? Support Synchronize Function for Parallel

Application

? Operation Mode Transfer Automatically between

Bypass Mode and DIV2 Mode (AT_Function)

? I2C is Available when Device in Present Mode

? 3-Error Charge Pump Switch Protection

? VBUS Voltage Too Low Error Protection before

Switch (VBUS_LOW_ERR)

? CFLY Short Error Protection Before Switch

(CFLY_DIAG)

? Converter Over-Current Protection (CON_OCP)

? 6-Way System Protection

? VBUS Over-Voltage Protection (VBUS_OVP)

? IBUS Over-Current Protection (IBUS_OCP)

? VOUT Over-Voltage Protection (VOUT_OVP)

? WRX Reverse Over-Current Protection

(WRX_IRE_OCP)

? VOUT Short Error Protection Before Charge

(VOUT_ERR)

? Junction Over-Temperature Protection

(TDIE_OTP)

Applications

? Smart Phones

? Tablet

? PC
