CON3 Lx Inputs
The MC33912 device has four high voltage inputs available for use in contact monitoring or as external wake-up inputs. The
terminals can be used as high voltage analogue inputs. For the L2, L3, L4 inputs, 33k ohm series resistors are used between the
connector and the device pins. L1 input is directly linked to the connector. Refer to
