DRV8243-Q1: Applying Logic=Hi when VM=0V

Masaru Oinaga

Part Number: DRV8243-Q1

Hello, Team,

In our application, normally VM will be 0V (i.e. voltage is not applied.)
Is it ok to apply Hi (=5V) to logic inputs (e.g. EN/IN1, DRVOFF, nSLEEP, etc) while VM=0V?

Best Regards,

Oinaga-san,

Yes, the inputs are "fail-safe" IOs which allow voltage to be present when VM = 0V. No issue and quite common in an application.

Regards,

Ryan
