MCP16502TAB-E/S8BVAO

Power Management - Specialized Overview

The MCP16502TAB-E/S8BVAO is a high-performance Power Management IC (PMIC) designed for SAMA5DX and SAM9X6 MPUs. It integrates four DC-DC buck converters and two auxiliary LDOs, supporting Dynamic Voltage Scaling (DVS). The device operates with an input voltage range of 2.7V to 5.5V and provides output voltages from 600mV to 3.7V. Key features include a 1MHz I2C interface, interrupt flags, and low quiescent current (<10µA in shutdown). It utilizes a 32-pin 5mm x 5mm VQFN package and functions within a temperature range of -40°C to +125°C.
