Abstract
A method for detecting an open load includes the use of a driver having at least one main power transistor connected to the load and one auxiliary transistor connected in parallel with the main transistor between a first power supply voltage reference and a second voltage reference. The method compares a first voltage present on a terminal connected to the load of the main transistor with a second voltage present on a terminal of the auxiliary transistor. A circuit for detecting an open load performs the method.
