100W USB Type C PD Power Monitoring Dongle Reference Design

PMP11474

Design files

Overview

The PMP11474 reference design measures the voltage and current present on a USB type C cable.  Current is monitored across a 5 mΩ sense resistor by an INA213 current amplifier.  Voltage is monitored by an LM321 amplifier.  These measurements are processed and displayed on a small LCD screen by an MSP430.

Features
  • Monitor voltage, current, and power on USB Type C bus
  • LCD display
  • One second refresh rate

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
