Pulse switched high side driver for vehicle sensor background
Systems, methods, and computer-readable media are disclosed for a pulse switched high side driver for vehicle sensor. An example method may include switching a transistor of a vehicle circuit to connect a first resistor to a vehicle sensor for a first time period in which exhaust gas temperature values of the vehicle are within a first range of exhaust gas temperatures values. The example method may also include switching, by providing a pulse-width modulation (PWM) signal with an on signal value, the transistor to connect a second resistor to a vehicle sensor for a second period of time in which exhaust gas temperature values of the vehicle are within a second range of exhaust gas temperatures values that are greater than the first range of exhaust gas temperature values, wherein the second resistor and vehicle sensor are also included in the vehicle circuit, wherein the second resistor is in parallel with a first resistor and connected between the transistor and the vehicle sensor. The example method may also include switching, by providing a pulse-width modulation (PWM) signal with an off signal value, the transistor to disconnect the second resistor from the vehicle sensor for a third period of time, the third period of time being greater than the second period of time. The example method may also include reading, using an analog to digital converter (ADC) an output of the vehicle sensor during or after the first period of time.
