A system and method for monitoring analog front-end (AFE) circuitry of an inductive position sensor. A redundant AFE channel is provided and alternatively utilized with a sine AFE channel or a cosine AFE channel of the AFE circuitry to obtain a voltage difference that may result in a detection angle error at the electronic control unit (ECU) of the inductive position sensor.

Various electronics systems may benefit from appropriate limitation of short-to-ground current. For example, sensor systems may benefit from a voltage sensing mechanism to minimize short-to-ground current for low drop-out and bypass mode regulators. A system can include a first power transistor configured to operate in a low drop-out mode. The system can also include a short to ground sensor configured to control current to the first power transistor. The short to ground sensor can be configured to limit a maximum short-circuit current below a predefined load current capability.
