DRV8844: EN pin

Cherry Zhou

Part Number: DRV8844

Hi team,

The customer is wondering if the EN pin can be directly pulled up with the v3p3out pin? Will it increase power consumption? Thanks.

Best Regards,

Cherry

    Hi Cherry,

    The absolute maximum current on the V3P3OUT is 10mA. The purpose of the resistor is to limit the current. As long as the current draw does not exceed 10mA, it should be okay to not include the resistor. the EN pin has a 100kohm pulldown which should keep the current below 10mA. 

    Regards,
