描述 Description

AXP229 is a highly integrated PMIC targeted at single cell Li-battery (Li-ion or Li-polymer) applications 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 requirements of power control.
AXP229 comes with an adaptive USB3.0 compatible 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, AXP229 provides multiple-channel 12-bit ADC for voltage/current temperature monitoring and integrates protection circuits such as OVP,UVP,OTP,and OCP. Moreover, AXP229 integrates a unique E-Gauge™ system which simplifies battery power measurement.

In addition, AXP229 contains a fast interface for the system to dynamically adjust output voltage and enable work mode switch in order to optimize battery life.

Importantly, AXP229 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.
 AXP229 is available in 8mm x 8mm x 0.75mm 68-pin QFN package.
