TLV1701-Q1: short circuit sink current

Part Number: TLV1701-Q1

Hi team,

May I ask the meaning of short circuit sink current?

Does the indicator in the red box of TLV1701-Q1 mean that the output terminal is short-circuited to the power supply, and there is a protection circuit inside to control the maximum sink current at 20mA? The device will not be damaged?

customer would like to confirm whether Vout short to 32V and this device won't be damaged.

  • The entry in the absolute maximum ratings table (section 7.1) guarantees that the device will not be damaged.

  • Hello Amelie,

    It won't be immediately damaged, but eventually damaged by thermal runaway.

    The output will limit current to about 20mA, but that is 20mA*32V=640mW dissipated across the output stage in a tiny package.

    Assuming the SC-70 package, 0.64W *  222.5C/W = 142°C (immediate) rise in temperature - so it will fail at some point.

    If it is a possibility that the output is shorted to the supply, then external current limiting (resistor) will be required, or, an external discrete transistor on a heat-sink.

    These are low powered devices and are not designed for high currents.
