Infineon Technologies has released the EZ-PD PMG1-B1 complementing the EZ-PD PMG1 family of high-voltage microcontrollers (MCU) with USB-C power delivery (PD).
The PMG1-B1 PD MCU is a single-chip solution that integrates a USB-C PD controller, a buck-boost battery charge controller, high voltage protection circuitry, and a microcontroller. It targets battery-powered applications, including power tools, personal care products, smart home appliances, and other portable devices.
The device is USB PD 3.1 certified and based on Infineon’s EZ-PD stack, ensuring compliance and interoperability with the latest USB-C and PD specifications. It combines a USB-C PD controller, a buck-boost battery charge controller, a 32-bit Arm Cortex-M0 processor with a 128 KB flash memory MCU, and a range of analog and digital peripherals, such as timers, UART, SPI, I²C interfaces, and PWMs. In addition, the PMG1-B1 integrates other high-voltage circuitry, such as V BUS-powered regulators, FET gate drivers, and advanced fault protection circuitry, including over-voltage, over-current protection, and V BUS to CC short-circuit protection, to ensure robust and reliable operation.
The PMG1-B1 PD MCU supports a wide input voltage range of 4 V to 24 V with 40 V tolerance and programmable switching frequency (150 to 600 kHz) to deliver up to 100 W (20 V, 5 A) power to the USB-C port.
