Revision 0.1

DESCRIPTION

AXP176 is a highly integrated power management

IC(PMIC) targeted at single cell Li-battery(Li-ion

or Li-polymer) applications that require multi-

channel power conversion outputs. It provides an

easy and flexible power management solution for

multi-core processors to meet the complex and

accurate requirements of power control.

AXP176 contains an USB-Compatible charger, 1

Buck DC-DC converter, 3 low dropout linear

regulator(LDOs), multi-channel 12-bit ADC including

voltage/current/temperature

monitoring.

ensure the security and stability of the power

system, AXP176 also provides self-protection

circuits such as over-voltage protection(OVP),

under-voltage protection (UVP), over-current

protection

(OCP)

and

over-temperature

protection(OTP).

The ‘Intelligent Power Select’ (IPS)™ circuit of

AXP176 distributes power safely and transparently

among the USB, Li-Battery and the application

system. It also allows application system to work

normally when only running at the external input

voltage and not the battery.

AXP176 has two input sources, including USB VBUS

input and battery. AXP176 provides TWSI(Two Wire

Serial Interface) to communicate with the

application processor. Through the interface,

processor can enable or disable the outputs, and set

the output voltage, as well as get the power status

and “fuel gauge” data, High-accuracy ADC makes it

convenient for consumer real-time control and

know the system power dissipation, which brings

them wonderful experience of device electricity

usage that never had before.

AXP176 is available in a 23-ball 2.61mm x 2.56mm

WLCSP package.

AXP176 has a very tiny package, so it is well to use

on wearable device such as smart watch, smart cup,

and so on.
