3 Description

The bq24188 is a highly integrated single cell Li-Ion

battery charger and system power path management

device that supports operation from either a USB port

or wall adapter supply. The power path feature allows

the bq24188 to power the system from a high

efficiency DC to DC converter while simultaneously

and independently charging the battery. The power

path also permits the battery to supplement the

system current requirements when the adapter

cannot. Many features are programmable using the

I2C interface. To support USB OTG applications, the

bq24188 is configurable to boost the battery voltage

to 5V and supply up to 1A at the input. The battery is

charged with three phases: precharge, constant

current and constant voltage. Thermal regulation

prevents the die temperature from exceeding 125°C.

•

30V Input Rating with Over-Voltage Protection

Supports 5V USB2.0/3.0 and 12V USB Power

Delivery

Small Solution Size In a 2.4mm x 2.4mm 36-ball

WCSP or 4mm x 4mm QFN-24 Package

–

Total Charging Solution Can be 50mm²or less

with WCSP
