Abstract
A monitoring device in integrated drive amplifiers intended to be driven by digital signals includes fault detection circuits giving a fault signal for such as excess temperature, overcurrent, or interruption and shortcircuiting in the load circuit. The input of the drive amplifier is connected to the output of a D-type flipflop (13) having a data input (D) and a clock input (C) intended for connection to a digital control system. Between the data input (D) and a potential corresponding to a logical ZERO there is connected a circuit (22,23) adapted for connecting the data input (D) to said potential during the interval between the operation signals when a fault signal is present.
