SLLIMM-NANO 3-phase inverter — what this module is
The STMicroelectronics STIPNS1M50SDT-H is a SLLIMM-NANO series 3-phase inverter module built around MOSFET output stages. It integrates the three half-bridge legs needed to drive a small brushless DC or permanent-magnet synchronous motor from a single 26-PowerSMD package with gull-wing leads. Rated for 500 V and 1 A, it targets appliance fans, pump drives, and low-power industrial actuators where board space is tight and a discrete six-MOSFET layout would consume too much area.
1000 Vrms isolation — where it connects
The 1000 Vrms isolation rating between the power stage and the control pins means this module can sit on the same PCB as a low-voltage MCU or DSP without a separate isolated power supply. The 26-PowerSMD gull-wing package is designed for reflow soldering onto a standard board; plan the creepage distance on the layout to maintain the isolation rating across the solder joints.
