Circuit for detecting an inadmissibly high current in an output stage |
摘要 |
A circuit for detecting an impermissibly high current in an output stage contains two transistors arranged in a bridge branch of a bridge circuit. A comparator compares the voltage obtained at the connection point of the two transistors with the voltage obtained at the center tap of a voltage divider connected to the power supply terminals. A switching transistor changes the voltage divider ratio of the voltage divider as a function of the switching signal of one of the transistors.
