Short circuit protect and detection


Thermal shutdown (auto reset) Detection condition: when.
external power active, output signal active, and output port
voltage less than 2V.
Open wire detect off-state leakage current0.1 mA When external power active and output signal inactive.
Detect reverse polarity voltage

Minimum 10V: Module must detect if the reverse polarity
external power supply voltage is greater than the value.

(1) Delay time is the time from the receipt of an output on or off command to the output actually turning on or off.
