LOW VOLTAGE ELECTRONIC MODULE INTERFACE

摘要

A low voltage electronic module interface, with a low voltage interface for an electronic module receiving a constant current from a body control module, the interface including a reverse current protection circuit (152); and a switch (154) operably connected in series with the reverse current protection circuit (152), the switch (154) being responsive to a status signal (144). The reverse current protection circuit (152) and the switch (154) form a low voltage electronic module interface circuit 150 having a resistance; and the resistance is selected so voltage across the low voltage electronic module interface circuit (150) is less than 2.70 Volts when the switch (154) is closed and the constant current (124) flows through the low voltage electronic module interface circuit (150).
