I2C Controlled 5A Buck-Boost NVDC Charger Converter for 2~4 Cell Battery with Dual-Input Power-Path and OTG Function
SC8984
SC8984 is a highly integrated buck-boost charger optimized
for 2~4 cell Li-ion and Li-polymer batteries. It integrates 4
switching power MOSFETs for the buck-boost operation, and
can support up to 22V input voltage, so can be used to
effectively manage the charging process no matter adapter
voltage is higher, lower or equal to battery voltage. The IC can
also discharge the cells and deliver desired output up to 22V.
The IC also integrates the battery FET to support the NVDC
(Narrow VDC) power path management. It provides a highdensity battery charging solution for the smart phone, tablet
and other portable devices and supports the USB type-C PD
(Power Delivery) charging easily.
The IC integrates a 11-bit ADC so user can monitor the
voltage and current for both inputs, system output and the
battery easily. Through its I2C interface, user can set the
charging / discharging mode easily, and program the charging
current, charging voltage, system voltage, reverse output
voltage, current limits and other parameters flexibly.
The IC supports internal current limit, over voltage protection,
output short protection and over temperature protections to
ensure safety under abnormal conditions.
The IC is in a 56-pin 2.9mm x 3.3mm WLCSP package.
