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 analogto-
digital converter. The high speed analog-to-digital
converter provides input and output voltage, current and
temperature information for the host. The host can
monitor the information by I2C serial interface.资料下载
