Monitoring Functions
An internal circuit ensures that all output transistors are turned-OFF if the supply voltage
is below the operating range.
A monitoring circuit for each output transistor detects whether the particular transistor is
active and in this case prevents the corresponding source transistor (sink transistor) from
conducting in sink operation (source operation). Therefore no crossover currents can
occur. Pulse-width operation is possible up to a maximum switching frequency of 1 kHz
for any load.
Depending on the load current higher frequencies are possible.
Protective Function
Various errors like short-circuit to +
V
S, ground or across the load are detected. All faults
result in turn-OFF of the output stages after a delay of 40
s and setting of the error flag
EF to ground. Changing the inputs resets the error flag.
Output Shorted to Ground Detection
If a high side transistor is switched on and its output is shorted to ground, the output
current is limited to typ 8 A. After a delay of 40
s all outputs will be switched off and the
error flag EF is set to ground.
Output Shorted to +
V
S and Overload Detection
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 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.
