Abstract
A process and circuit for the connection of electrical loads to the terminals of an amplifier, and for detection of a possible connection defect of said electrical loads. An electrical load is connected to two terminals of the amplifier according to a complete-bridge mounting. At least one second electrical load is connected according to a half-bridge mounting. In a preliminary phase, reference values representative of the currents flowing in each of the connection branches are memorized and measured and there are detected from these measurements and memorized, the reference values of the currents flowing through each of the terminals. During operation of the amplifier, the current passing through each of the two terminals is measured and compared to the corresponding memorized reference value, so as to detect therefrom the connection branch or branches which suffer a connection defect of an electrical load.
