Monitoring device for integrated driver amplifiers

摘要

A monitoring device in integrated driver amplifiers is controlled by digital signals. This monitoring device comprises error detector circuits which generate an error signal in the event of an excessive temperature, in the event of an overcurrent, in the event of an interruption or in the event of a short circuit in the load circuit. The input of the driver amplifier is connected to the output of a D-type flip flop (13) which exhibits a data input (D) and a control input (C) which can be connected to a digital control system. Between the data input (D) and a potential which corresponds to the logical _0_, a circuit (22, 23) is provided by means of which the data input (D) is dropped to the _0_ potential during the intervals between the operating signals when an error signal is present. <IMAGE>
