TLE 5207
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 µs 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 11 A. After a delay of 40 µs 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 µs 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.
