Claim 17:
18. A non-transitory, computer-readable, medium having non-transitory, computer-readable instructions encoded thereon for monitoring a high voltage electrical system in a vehicle using an interface circuit that provides isolation between a high voltage component of the vehicle and a control module that, when executed by control circuitry cause the control circuitry to:
receive, at a field effect transistor of the interface circuit, an input at a first voltage from the high voltage component;
receive, at a Zener diode of the interface circuit, an output from the field effect transistor; and
receive, at an opto-isolator of the interface circuit, an output from the Zener diode, and, in response to receiving the output, output a signal at a second voltage to the control module.
