STMicroelectronics EVLSERVO1 STSPIN32G4-Based Reference Design

STMicroelectronics EVLSERVO1 STSPIN32G4-Based Reference Design is a compact reference design for driving low-voltage, high-current servo motors. The STMicroelectronics EVLSERVO1 features the STSPIN32G4, a system-in-package that combines a triple high-performance half-bridge gate driver with programmable features, an STM32G431 microcontroller, and advanced power management that generates the required internal supply. This is housed in a 9mm x 9 mm VFQFPN package. The design's small 50mm x 80mm x 60mm form factor is achieved by stacking the power and control boards.
