This household water pump reference design includes microcontrollers (MCUs), photocouplers, comparators, and gate drivers. Comparators compare and amplify signal data from water-level sensors. Photocouplers and gate drivers prevent high voltages from affecting the system. They receive the signal and provide high efficiency for motor driving control.

System Benefits:

  • This system provides low power consumption and low noise for a water pump
  • Renesas’ photocoupler and gate driver combined with an inverter provide high efficiency
  • This system features solutions that are compact, provide high efficiency and are environment-friendly
