Patent abstract

The present teachings generally include a method of controlling a relay. The method generally includes momentarily initiating a pull-in pulse when an input signal indicates a first state. A sense resistor controller is activated based on the pull-in pulse. A current flow is controlled to bypass a sense resistor and flow to the relay based on the activation of the sense resistor controller. The relay is controlled based on the current flow.
