Abstract
Systems, devices, methods, and techniques are disclosed for open load detection in the connections coming from output stages of electrical systems. In some examples, an open load detection circuit includes a circuit output configured to provide an output voltage to a load, a first switch coupled to the circuit output and coupled to a first supply voltage configured to switch the load, and at least one delta voltage circuit coupled to the circuit output configured to provide a delta voltage. The at least one delta voltage circuit is coupled to the first switch to create a reduction in voltage magnitude of the first supply voltage to a switch voltage of the first switch provided to the circuit output. The open load detection circuit also includes at least one current source coupled to the circuit output to provide a current to the circuit output.
