DESCRIPTION

AXP228 is a highly integrated PMIC targeted at single

cell Li-battery (Li-ion or Li-polymer) appli-cations

that require multi-channe power conversion outputs.

It provides an easy and flexible power management

solution for multi-core processors to meet the

increasingly complex and accurate Require-

ments of power control.

AXP228 comes with an adaptive USB3.0-co-mpatible

Flash Charger that supports up to 94% efficiency and

2.2A charge current. It also provides 21 power output

channels (including 5-CH DCDC, with efficiency up to

95%). To ensure the security and stability of the

power system, AXP228 provides multiple-channel 12-

bit ADC for voltage/current temperature monitoring

and integrates protection circuits such as OVP, UVP,

OTP, and OCP. Moreover, AXP228 integrates a unique

E-Gauge

™ system which simplifies battery power

measurement.

In addition, AXP228 contains a fast interface for the

system to dynamically adjust output voltage

and enable work mode switch in order to optimize

battery life.

Importantly, AXP228 also features an IPS

™

(Intelligent Power Select) circuit that transparently

selects power path among USB, external adaptor, Li-

battery, and system load, allowing the system

to function normally when only running on external

input power and not the battery.

AXP228 is available in 8mm x 8mm x 0.75mm 68-pin

QFN package.
