Output Shorted to +
An internal circuit detects if the current through the low side transistor is higher than 4 A
typ. In this case all outputs are turned off after 40 s and the error flag EF is set to
ground.
At a junction temperature higher than 160 C the thermal shutdown turns off, all four
output stages commonly and the error flag is set without a delay.
Open Load Detection
The output Q1 has a 10 k
resistor. If E1 and E2 are high, all output power stages are turned-OFF. In case of no
load between Q1 and Q2 the output voltage Q1 is
be detected by two comparators and an error flag will be set after a delay time of 40 s.
Changing the inputs resets the error flip flop.
