Household Water Pump

Renesas’ reference design system provides low power consumption and low noise for a water pump

Image of Renesas' Household Water PumpRenesas’ 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.
