The AXP192 provides an easy to use, fully integrated,
ultra-flexible power solution for single cell Li-Ion/LiPolymer battery and multiple-power applications.
AXP192 contains an USB-Compatible charger, 3 BuckDC-DC converter, 4 low dropout linear regulator,
voltage/ current / temperature monitor and multichannel 12 - Bit ADC. To ensure power system work
stably, AXP192also contains self-protection circuits suchas OVP / UVP, OTP and OCP .
The “Intelligent Power Select”(IPS)™ circuit of AX192
distributes power safely and transparently between theUSB, external AC adapter, Li-Battery and the application
system. It also allows the application system workwithout battery or discharged battery.
AXP192 has three input source, including externaladapter, USB VBUS input and battery. It also supports
use of the rechargeable backup battery.
AXP192 provides TWSI(Two Wire Serial Interface) tocommunicate with the application processor. Throughthe interface, processor can enable or disable theoutputs, and set the output voltage, as well as get thepower status and “fuel gauge” data, High-precision ADC
makes it convenient for consumer real-time control andknow the system power dissipation, which brings themwonderful experience of device electricity usage thatnever had before.
