ADM1014 Datasheet (Analog Devices) - Dual PCI Hot-PlugTM Controller

ADM1014, Dual PCI Hot-PlugTM Controller

The ADM1014 operates from a +12V and +3.3V AUX supply and controls five independent supplies (+3.3V, +3.3VAUX, +5V, +12V and *12V) on two separate channels (A and B).

The power switches for the +3.3VAUX, +12V and *12V supplies are integrated onto the chip, and internal current limit
