Abstract

Motor driver circuitry including driver transistors coupled to first and second output terminals, gate driver circuitry with outputs coupled to gate terminals of the driver transistors, controller circuitry coupled to the gate driver circuitry, a trip limit current source, an open-load limit current source, comparator circuitry, and fault detect circuitry. The comparator circuitry is coupled to the driver transistors, to the trip limit current source, and to the open-load limit current source. The comparator circuitry compares a drive current at the driver transistors with a trip limit current responsive to a signal from the controller indicating a standstill state, and configured to compare the driver current with an open-load limit current responsive to the signal indicating a motor running state. The fault detect circuitry has an input coupled to the comparator output and has a fault output.
