TPS2640: spec check

Part Number: TPS2640

Tool/software:

Hi 

The customer currently uses the TPS26400RHFR eFuse circuit as follows: Why is the FLT pin pulled Low in No Load? This causes LED 29 to light up when power is turned on without connecting any load.

  • Hello Gareth,

    Can you keep VIN and VOUT on same origin and check if VOUT>VIN?

    This could assert the FLT pin on event of reverse current.

    What's the value of series resistor connected to FLT pin?

    Thanks 

    Amrit
