MC34825EPR2

Controllers Overview

The MC34825EPR2 is a Micro-USB interface IC supporting the Universal Charging Solution (UCS) and wired accessories. It integrates analog switches for USB, UART, and audio multiplexing, alongside an internal power MOSFET for charging control. Key electrical parameters include a VDD supply voltage range of 2.7 V to 5.5 V and a VBUS input range up to 28 V with overvoltage protection at 7.0 V typical. The device features a 5-bit ADC for ID resistance detection, I2C interface support up to 400 kHz, and operates within a temperature range of -40 °C to +85 °C. Quiescent current in standby mode is typically 9.0 µA.
