AXP216 is a highly integrated 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 increasingly complex and accurate requirements of power control.


AXP216 comes with an adaptive USB3.0-compatible Flash Charger that supports up to 94% efficiency and 2.2A charge current. It also provides 11 power output channels (including 5-CH DCDC, with efficiency up to 95%).

To ensure the security and stability of the power system, AXP216 provides multiple-channel 12-bit ADC for voltage/current temperature monitoring and integrates protection circuits such as OVP, UVP, OTP, and OCP. Moreover, AXP216 integrates a unique E-GaugeTM system which simplifies battery power measurement.


In addition, AXP216 contains a fast interface for the system to dynamically adjust output voltage and enable work mode switch in order to optimize battery life.


Importantly, AXP216 also features an IPSTM(Intelligent Power Select) circuit that transparently selects power path among USB, external adapter, Li-battery, and system load, allowing the system to function normally when only running on external input power and not the battery.


AXP216 is available in 8mm x 8mm x 0.75mm 68-pin QFN package.

  • Tablets, smartphones, smart TVs, DVRs
  • UMPC and UMPC-like, student computers
