3 Description

– 91.8% charge efficiency at 2A from 9-V input

for 1-cell battery

The BQ25303J is a highly-integrated standalone

switch-mode battery charger for 1-cell Li-ion and Li-

polymer batteries. The BQ25303J supports 4.1-V to

17-V input voltage and 3-A fast charge current. The

integrated current sensing topology of the device

enables high charge efficiency and low BOM cost.

The best-in-class 200-nA low quiescent current of the

device conserves battery energy and maximizes the

shelf time for portable devices. The BQ25303J is

available in a 3x3 WQFN package for easy 2-layer

layout and space limited applications.

•

Single input to support USB input and high voltage

adaptors

– Support 4.1-V - 17-V input voltage range with

28-V absolute maximum input voltage rating

– Input Voltage Dynamic Power Management

(VINDPM) tracking battery voltage

High integration

– Integrated reverse blocking and synchronous

switching MOSFET

– Internal input and charge current sense

– Internal loop compensation
