ABSTRACT:
A plug-in module receives both primary and alternate power via mating connectors on the module and on the backplane. Multilevel connectors are used so that a module being inserted first receives alternate power and ground before primary power and signal connections are made. The initial connect to the alternate power supply directs the transient current to the alternate power supply through an isolating PN junction diode having a forward bias voltage drop of about 0.8 volts. When the module is fully inserted, the module is connected to both the primary and alternate power. Within each module the associated electrical load is now connected directly to the primary power bus. To prevent transient currents produced by the hot insertion of other plug-in modules from affecting the voltage level on the power bus, the primary voltage supply is connected to the primary power bus via a Schottky diode having a forward bias voltage of approximately 0.4 volts. Due to the lower voltage drop by the Schottky diode, the isolating PN junction diode is no longer forward biased when the primary power is connected to the module. The alternate power bus will thus supply power to the module only during the short time from initial insertion into the backplane until the module is fully inserted.
