Assignee: CIRRUS LOGIC INC.
Field: Chemical engineering (Chemistry)
Classification: CPC B  H | IPC B  H

Claim 0:
1. Circuitry for driving a load, the circuitry comprising:
driver circuitry configured to generate a drive signal, based on an input signal to the driver circuitry, for driving the load; and
commutator circuitry for coupling the driver circuitry to the load, wherein the commutator circuitry is configured to alternate between commutation states in response to a level of the drive signal meeting a drive signal threshold or in response to a level of the input signal meeting a first input signal threshold,
wherein the circuitry is configured to apply an offset to the input signal when the input signal is below a second input signal threshold so as to increase a minimum level of the drive signal above the drive signal threshold or to increase a minimum level of the input signal above the first input signal threshold.
