Microchip Technology EV18H47A MCS MCLV-48V-300W Development Board

Microchip Technology EV18H47A MCS MCLV-48V-300W Development Board Drives a low-voltage (12V to 48V) three-phase Permanent Magnet Synchronous Motor (PMSM) or Brushless DC (BLDC) motor. This development board motor up to 25A RMS continuous per phase at 25°C. The EV18H47A MCLV-48V-300W development board consist of three-phase motor control power stage. This development board features optional analog sensor (e.g., thermistor) interface circuit and hall sensor interface. The EV18H47A MCLV-48V-300W development board provide overvoltage and current protection circuits.
