Abstract: An example non-transitory machine-readable storage medium includes instructions that, when executed, configure processor circuitry to at least: determine a first delay corresponding to an amount of time for a first pulse to reach first phase circuitry; determine a second delay corresponding to an amount of time for a second pulse to reach second phase circuitry; determine a third delay corresponding to an amount of time for a third pulse to reach third phase circuitry, wherein one or more of the first phase circuitry, the second phase circuitry, and the third phase circuitry are located a non-uniform distance from the processor circuitry; and transmit, based on the delays, the pulses to the respective phase circuitry such that a first time period between the first pulse and the second pulse is equal to a second time period between the second pulse and the third pulse.

Abstract: An example apparatus includes: a phase circuit configured to receive a pulse of a pulse width module (PWM) signal; provide, after receiving the pulse, an output voltage to a load; exhibit a fault; in response to the fault corresponding to a first category, transmit a first code voltage in a current sense (CS) signal; in response to the fault corresponding to a second category, transmit a reference voltage in the CS signal; receive, after transmission of the reference voltage, a tristate voltage in the PWM signal; and transmit, after receiving the tristate voltage, a second code voltage in the CS signal based on a type of the fault and the second category.
