Infineon Technologies launched the EZ-PD™ PMG1-B2, the industry’s first highly integrated single-port USB Type-C Power Delivery (PD) microcontroller with an integrated 55V buck-boost controller for 2- to 12-cell (2S to 12S) lithium-ion battery charging. The solution complies with the latest USB Type-C and PD specifications and supports a wide input voltage range from 4.5 to 55 V and a programmable switching frequency from 200 to 700 kHz.
The EZ-PD PMG1-B2 is ideal for high-voltage battery charging in embedded systems across consumer, industrial, and communications applications that are powered via USB-C and utilize the available MCU functions. Target applications include cordless power tools and gardening tools, cordless vacuum cleaners, cordless kitchen appliances, e-bikes, e-kick scooters, drones and robots, and more.
At the core of the EZ-PD PMG1-B2 is a 32-bit Arm® Cortex®-M0 processor with a 128 KB flash memory and 8 KB SRAM, providing the processing capability needed for customizable USB PD applications. The device integrates various analog and digital peripherals, including ADCs, PWMs, UART/I²C/SPI interfaces, and timers, reducing the bill of materials as well as the space required on the PCB. Development is simplified through a comprehensive SDK, fully interoperable USB PD stacks, and a proprietary software suite for easy customization. Integration of MCU, USB PD, high-voltage LDO, buck-boost battery charger, and battery protection blocks, including VBAT to GND short protection in PMG1-B2, helps reduce system BOM cost and simplifies the design for USB-C-based battery powered applications. The solution comes in a 68-pin QFN package and supports an ambient temperature range of -40°C to +85°C and a maximum operating junction temperature of 125°C.
Based on the EZ-PD PMG1-B2, Arrow Electronics and Infineon will soon introduce a 240 W USB-C PD 3.2 reference design that combines the new controller with Infineon’s PSOC™ C3 and 100 V CoolGaN™ G5 transistors to enable compact, high-efficiency battery-powered motor control systems. Supporting fast charging for 2- to 12-cell Li-ion battery packs and advanced motor drive control, the demo board targets applications such as e-bikes, e-scooters, power tools, home appliances, garden equipment, and robotics.
