Abstract

A common problem experienced by electronic systems is when parasitic power from an attached device or accessory inhibits the proper turn-on of the primary system when it is powered down and connected to the device or accessory with active power. A device is described herein which can be added to the primary system and essentially clamps the parasitic power sources to a negligible level, thus allowing proper power up sequencing for the primary device.
