AXP192中文资料Single Cell Li-Battery and Power System Management IC数据手册power规格书

描述 Description

The AXP192 provides an easy to use, fully integrated, ultra-flexible power solution for single cell Li-Ion/Li-Polymer battery and multiple-power applications.
AXP192 contains an USB-Compatible charger, 3 Buck DC-DC converter, 4 low dropout linear regulator, voltage/ current / temperature monitor and multi channel 12 - Bit ADC. To ensure power system work stably, AXP192also contains self-protection circuits such as OVP / UVP, OTP and OCP .
The “Intelligent Power Select”(IPS)™ circuit of AX192 distributes power safely and transparently between the USB, external AC adapter, Li-Battery and the application system. It also allows the application system work without battery or discharged battery.
AXP192 has three input source, including external adapter, USB VBUS input and battery. It also supports use of the rechargeable backup battery.
AXP192 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-precision 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.
