3 Description

The BQ25630 is a highly-integrated 5A switch-mode

battery charge management and system power path

management device for single cell Li-Ion and Lipolymer

batteries. The solution is highly integrated

with built-in current sensing, loop compensation,

input reverse-blocking FET (RBFET, Q1), switching

FETs (HSFET - Q2 and LSFET - Q3), and battery

FET (BATFET, Q4) between system and battery.

It integrates a USB Type-C controller with Dual-

Role Power with Try.SNK and Try.SRC support. It

uses NVDC power path management, regulating the

system slightly above the battery voltage without

dropping below a configurable minimum system

voltage. The low impedance power path optimizes

efficiency, reduces battery charging time and extends

battery life during discharging phase, and the ultra-low

0.15μA ship mode current extends battery shelf life.

The I2C serial interface with charging and system

settings makes the BQ25630 a truly flexible solution.
