Product Introduction

test

The PM20025G-08 series uses an ARM® Cortex®-M0 core with a maximum operating frequency of up to 48MHz, and is equipped with 32Kbyte of Flash and 4Kbyte of SRAM. Built-in three-phase brushless gate driver, capable of operating at up to 36V, is designed to drive MOSFETs with a 6N structure. With these rich peripherals, PM20025G-08 is particularly suitable for applications such as square wave/FOC drive control for BLDC/PMSM motors


The PM20025G-08 series of chips are motor-specific MCUs developed by MetaWells . Users can refer to the "PM10025A User Manual" for further understanding of the functionality of this series of chips
