Aufwecksystem für auf einem Fahrzeug unterstützte elektronische Komponenten

A power control assembly limits the amount of leakage current absorbed by a device (30) supported on a vehicle when the device is in a sleep mode. The described example includes a switch (40) between a vehicle power source (54) and a power supply (50, 52) for the peripheral device. A locking portion...

Zusammenfassung:	A power control assembly limits the amount of leakage current absorbed by a device (30) supported on a vehicle when the device is in a sleep mode. The described example includes a switch (40) between a vehicle power source (54) and a power supply (50, 52) for the peripheral device. A locking portion (44) controls operation of the switch (40) so that selected portions of the device (30) are isolated from the vehicle power source (34) when the device (30) is in a sleep mode. A wake up signal received by a communication bus transceiver (32) activates the switch locking portion (44), which in turn allows the isolating switch (40) to be electrically closed and kept in the closed condition until the controller (54) of the device determines that the device should enter the sleep mode.
