ソリューション概要
This is a complete solution for controlling a variable-speed 3-phase 250 W BLDC compressor motor used in refrigeration systems, air compressors, air conditioning units and more.
Built around a system-in-package, this highly energy-efficient solution offers the highest integration as well as full protection and higher performance (2-shunt version) with respect to other solutions on the market.
At the heart of this three-phase inverter solution is the STSPIN32F0601 controller which embeds a Mainstream STM32F031 Access line microcontroller, a 600 V 3-phase gate driver powered by a high-performance VIPER122 high-voltage converter in a buck configuration and an L78L33 three-terminal positive voltage regulator.
The power section is implemented through an STD8N60DM2 N-channel 600 V Power MOSFET from the MDmesh™ DM2 fast-recovery diode series for further optimization.
This extremely integrated solution helps designers to reduce PCB area and their overall bill of materials.
