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.
