Introduction

AXP2101 is a highly integrated power management IC designed for single-cell lithium battery applications requiring multi-channel power output. It provides a simple and flexible power management solution for multi-core processors to meet complex and precise power control requirements. AXP2101 supports linear charging and provides 16-channel power output, including 5-channel DC-DC converters and 11-channel LDOs. To ensure system safety and stability, AXP2101 integrates multi-channel 14-bit ADCs for voltage and temperature monitoring, along with protection circuits including overvoltage protection, overcurrent protection, and over-temperature protection. In addition, AXP2101 features a unique E-Gauge coulomb counter system, making battery level monitoring simple and accurate. AXP2101 supports a two-wire serial interface and a reduced serial bus, enabling the system to dynamically adjust output voltage, charging current, and configure interrupt conditions.
