Data Sheet
If a high side transistor is switched on and its output is shorted to ground, the output
current is internally limited. After a delay of 50 µs all outputs will be switched-OFF and
the error flag is set.
If a low side transistor is switched on and its output is shorted to the supply voltage,
the output current is internally limited. After a delay of 50 µs all outputs will be
switched-OFF and the error flag is set.
An internal circuit detects if the current through the low side transistor exceeds the
trippoint
At a junction temperature higher than 150 °C the thermal shutdown turns-OFF, all four
output stages commonly and the error flag is set with a delay.
