This household water pump reference design includes microcontrollers (MCUs), photocouplers, comparators, and gate drivers. Comparators compare and amplify signal data from water-level sensors. The RL78/G13 is a 16-bit MCU that is ideal for system control and controlling an LCD. 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
