Infineon introduces a USB PD 3.1 high-voltage microcontroller

Posted 4 August 2021

Infineon Technologies introduced a new high-voltage microcontroller (MCU) with USB Power Delivery (USB PD) 3.1 support.

EZ-PD PMG1 (Power Delivery Microcontroller Gen1) is Infineon’s first generation of USB PD MCUs targeting any embedded system that provides or consumes power with high-voltage up to 28 V (140 W). The device supports higher power capabilities defined in the USB PD 3.1 specification and leverages the MCU to provide additional control capability. The new products are ideal for consumer, industrial and communications markets for applications such as smart speakers, routers, power and garden tools.

The PMG1 family integrates a USB PD stack to enable reliable performance and interoperability. It features an Arm Cortex-M0/M0+ processor with up to 256 KB Flash memory and 32 KB SRAM, USB full-speed device, programmable general purpose input/output (GPIO) pins, gate drivers, low drop out (LDO) regulators and high-voltage protection circuits.

PMG1 MCU also provides hardware and firmware protection, including over-voltage and over-current protection, short circuit and reverse current protection, secure firmware boot and signed firmware update.
