Abstract: A timer circuit is provided comprising: a resistor; a programmable gain circuit coupled to amplify the reference level based upon a resistor and a selected gain; a detection circuit coupled to identify the amplified reference level based upon a resistor; a selection circuit configured to select the gain based at least in part upon the identified amplified reference level based upon a resistor; a comparator circuit configured to transition between providing a signal having a first value and providing a signal having a second value based at least in part upon comparisons of a reactive circuit element excitation level with the amplified reference level based upon a resistor and with a second reference level; and reactive circuit element excitation circuit configured to reverse excitation of the reactive circuit element in response to the comparator circuit transitioning between providing the signal having the first value and providing the signal having the second value.

Abstract: The present disclosure relates to a gate driver system suitable for driving the gate voltage of one or more transistors. The gate driver system is configured to operate in a first state when the current conducted by the transistor is relatively low and in a second state when the current conducted by the transistor is relatively high. In the second state, the gate voltage is set such that the source voltage at the transistor establishes a lower voltage across a source-driven load than is the case when operating the first state, thereby reducing the level of power consumption in the load during second state operation.
