Description
AXP2101 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 outputs. It provides an easy and flexible power management solution for multi-core processors to meet the complex and accurate requirements of power control.
AXP2101 supports switch charge which function should be customized. Besides, it supports 15 channel power outputs which include 4 channel DCDCs and 11 channel LDOs. To ensure the security and stability of the system, AXP2101 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, AXP2101 features a unique E-Gauge™ (Fuel Gauge) system, making power gauge easy and exact.
AXP2101 supports TWSI and RSB for system to dynamically adjust output voltages, charge current and configure interrupt condition.
