TPS1H000-Q1: Leakage spec on Delay pin

Lee, Sam
Expert 6045 points
Part Number: TPS1H000-Q1

Hi team,

 

A customer asks a few question about TPS1H000-Q1. Would you please answer?

 

-. When using Auto-Retry mode, the external pull up is required at DELAY pin. What is the leakage current spec on the DELAY pin under below condition?

   Vs = 5V

   Vin = Vdiag_en = 0V

   DELAY pin has 10k pullup to Vs(5V)

 

-. When OUTPUT Short to Battery occurs, is the output automatically disabled without needing the protection diode? Otherwise, is a diode required to prevent reverse current?

Thanks,

Sam Lee

    Hi Sam Lee, 

    1- I believe we do not provide this information for the devices. However, let me research a bit further and I will get back to you with a final confirmation here. I want to see if this information has been provided before and how.

    2 -  The blocking diode is placed on the system in order to protect the system in the condition of reverse battery conditions. The blocking diode serves as protection to the high side switch, load, and any connected MCU in case of a short-time reverse current event.

    Hi Sam Lee, 

    Since the Delay pin is an output pin, there won't be leakage current on this pin. In addition, if a pull-up resistor is used, there will not be any current drawn from the pin. 

    Sincerely,
