RT9759

Smart Cap Divider Charger

General Description

Features

 External OVP Control and Regulation

 High Absolute Maximum Rating of 40V

 Fast Reaction Time 100ns and Fast Turn Off

Time 100ns

The RT9759 is a high efficiency and high charge current

charger. The efficiency is up to 97.8% when VBAT =

4.2V, IBAT = 2.5A and the maximum charge current is

up to 8A. The device integrates smart cap divider

topology, external over-voltage protection control, an

input reverse blocking NFET and 2-way regulation, a

dual-phase charge pump core, 15-way protection, 7-

way system alarm and 9-Channel high speed analog-

to-digital converter. The high speed analog-to-digital

converter provides input and output voltage, current and

temperature informations for host. The host can monitor

the informations by I²C serial interface.

 VBAT Voltage Regulation (VBAT REG)
