TPS4H160-Q1: 7.3.7.3 Protection for Loss of Power Supply

Part Number: TPS4H160-Q1

Tool/software:

Hi all,

I would like to know the behavior of VS (20-23pin) when the power supply is OFF (0 V).

From "7.3.7.3 Protection against loss of power" in the data sheet,

I understand that the output is shut down regardless of the input level of IN1-4 (3-6pin).

Regarding the other input pins (SEH: 7pin, SEL: 8pin, DIAG_EN: 14pin) Behavior under the same conditions is not specified in the data sheet.

These pins are the same as IN1-4, is it correct to understand that there is no problem in operation even if a High or Low is input under the condition that the power is not turned on?

Best regards,

Ryusuke

  • Hi Ryusuke,

    If there is no power on VS than the TPS4H160 and all of its functionality turn off and the gate will not be able to turn on.

    The other input pins will not be able to change the device status or turn the device on either.

    Best Regards,
