DRV8305-Q1: PWRGD Signal

Part Number: DRV8305-Q1

Hi Champs,

Do we understand right that the Power Good function of the PWRGD pin can only be active at DRV8305 if the included Vreg is active? That means the DRV8305NE does not provide a Power Good indication on the PWRGD pin since the Vreg is not active, right?

The PWRGD does only indicate the Watchdog Fault to reset the MCU on the DRV8305NE, also correct?

Best regards,

Simon Jagla

  • Hi Simon,

    PWRGD is used to indicate WATCHDOG FAULT on both VREG active (3, 5) and VREG inactive (N) devices. It is also used to indicated VREG undervoltage on VREG active devices (3,5).
