EVAL_PMG1_B1_DRP kit guide
About this document
Scope and purpose
The EVAL_PMG1_B1_DRP is an evaluation kit for the EZ-PD™ PMG1-B1 USB Power Delivery (PD) microcontroller
(MCU) with an integrated buck-boost battery charger. EZ-PD™ PMG1-B1 is targeted for battery-powered
applications that are powered by USB-C PD such as cordless power tool chargers, wireless speakers, and
portable electronics. EZ-PD™ PMG1 (Power Delivery Microcontroller Gen1) is a portfolio of high-voltage USB-C
PD microcontrollers. These MCUs include Arm® Cortex® CPU core, USB-C PD controller, and configurable
integrated analog and digital peripherals. EZ-PD™ PMG1-B1 is targeted at embedded systems that power from
USB-C port and need an MCU to implement the product features.
Intended audience
This document is intended for designers who want to Sink or Source power through the USB-C PD port in
applications such as the cordless power tool charger, wireless speakers, and portable electronics. The kit can
be used to sink up to 100 W and source up to 27 W. The kit can also be used to charge 2 cell-5 cell batteries, and
the battery charging algorithm is implemented as part of PMG1-B1 SDK in ModusToolbox™ software.
