This document is about the functional block diagram of ADI's ADM1014 product. It introduces the functional features of the product, such as power supply voltage range, current limiting range, overcurrent protection, etc.
The ADM1014 is a dual PCI voltage bus controller designed to allow hot-plugging of adapter cards into and out of an active or passive backplane. The device requires only four external power MOSFETs and a few discrete components to provide a complete power-control solution for two PCI slots. It 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).
| Operating Temperature Range | 0°C to +70°C |
|---|---|
| Storage Temperature Range | -65°C to +150°C |
| Continuous Power Dissipation | 667mW |
| 12V Output Current | 3A |
| -12V Output Current | 0.8A |
The device controls five independent supplies: +3.3V, +3.3VAUX, +5V, +12V, and -12V.
The power switches for the +3.3VAUX, +12V, and -12V supplies are integrated onto the chip.
The current limits are set by a single resistor to GND connected to the OCSET pin.
