TPS22965 Output Short

TPS22965: Output short

Part Number: TPS22965

Hi

  If TPS22965 Vout is short to GND, will it take any protection, due to no OTP/OCP inside? There is a discharge resistor internally. If pin 3 (ON) is High, and test SCP, will TPS22965 protect? or the protection depends on upstream VR OCP?

  Guessed on this case, the discharge resistor is off because ON pin high, right?

    Hi Alan,

    The TPS22965 does not have OTP (Over Temperature Protection) or OCP (Over Current Protection), hence the device will not protect itself. For QOD you are correct. The QOD resistor will only activate when the device is switched OFF (ON pin low).

    A similar component you can consider is the TPS22975. This device has OTP, but no OCP. The TPS22975 is pin to pin compatible with the TPS22965, and their specifications are nearly identical.

    Regards,
