Description
AXP717 is a highly integrated power management IC (PMIC) targeting 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 complex and accurate requirements of power control.
AXP717 supports NVDC switch charge. Besides, it supports 17 channel power outputs which include 3 channels DCDC and 14 channels LDO. To ensure the security and stability of the system, AXP717 provides multiple channels 14-bit ADC for voltage/temperature monitor and integrates protection circuits such as over-voltage protection (OVP), over-current protection (OCP) and over-temperature protection (OTP). Moreover, AXP717 features a unique E-Gauge™ (Fuel Gauge) system, making power gauge easy and exact.
AXP717 supports TWSI and RSB for system to dynamically adjust output voltages, charge current and configure interrupt condition.
