Introduction
1. Introduction
AXP203 is a highly integrated power management IC that provides easy and flexible power solution for
applications that powered by single cell Li-battery (Li-ion or Li-polymer) and require multi-power outputs as well.
It has fully met the increasingly complex needs of application processors on accurate power control.
AXP203 integrates an adaptive and USB-compatible PWM charger, two step-down converters (Buck DC-DC
converter), five LDO regulators, multiple voltage/current/temperature 12-bit ADCs, and four configurable GPIOs.
It also features protection circuitry such as over/under-voltage protection(OVP/UVP), over-temperature
protection (OTP), and over-current protection (OCP) to guarantee the power system security and stability.
The Intelligent Power Select of AXP203 (Intelligent Power Select, IPS™) can allocate power safely and
transparently among USB, external AC adapter, Li-battery, and application loads. It also enables applications to
work normally with only external input power but no batteries (or battery deeply discharged/damage).
AXP203 is capable of three input methods: external adaptor input, USB input and battery input. It also supports
rechargeable backup batteries.
In addition, AXP203 comes with a Two Wire Serial Interfaces (TWSI), through which the application processor is
capable of enabling/disabling some power outputs, programming the voltage, and visiting internal registers and
measurement data (including Fuel Gauge). High accuracy (1%, depending on the 1% accuracy of BIAS resistors) of
power measurement enables consumers to know more clearly the real-time power consumption, and provides
them with unprecedented experience of power management.
Applications:
Portable Devices: Smart Phone, PMP/MP4, Digital Camera, Camcorder, PND, PDA, PTV
Mobile Internet Devices xPad, MID
Digital Photo Frame, Portable DVD Player, Ultra-Mobile PC(UMPC) and UMPC-like, Entertaining and
Education Machine
Application Processor Systems
Other battery and multi-power application system
