DRV8305-Q1: WAKE-Pin specification

Genius 16285 points
Part Number: DRV8305-Q1

Hi all

My customer is working on a design with the DRV8305-Q1 and they have this question:

They want to connect the WAKE-pin to their logic 3.3V supply and are not sure if they should use a series-resistor / what value they should select for this series resistor.

In the Datasheet they find they should limit the current into this pin to 1mA and on page 33 of the Datasheet they find the level at this pin should be greater than 3V.

However the input impedance for this pin is not specified.

Can you clarify ?

Best regards

Ueli
