ABSTRACT:
A frequency-controlled load driver circuit includes a steady-state and a transient operational mode. A switching driver switches a load current to a solenoid at a set switching frequency during a steady-state operational mode. An analog-to-digital converter (ADC) oversamples a sense resistor voltage an integer number of times within each period of the switching frequency. A control circuit sets the switching frequency of the driver during the steady-state operational mode by providing predetermined switching times. The control circuit disables switching during the transient mode. Dither can be applied during the steady-state mode.
