This document introduces the basic functions and characteristics of HIP1011 PCI hot plug controller, including four independent power control, overcurrent protection and undervoltage protection.
The HIP1011 is a PCI Hot Plug voltage bus control IC that manages four independent supplies (+5V, +3.3V, +12V, and -12V) for hot‑plugging adapter cards. It includes internal MOSFET switches for the ±12 V supplies and uses external sense resistors for over‑current protection on the +5 V and +3.3 V rails.
The document provides pin descriptions, absolute maximum ratings, detailed electrical specifications, typical performance curves, and mechanical dimensions for the 16‑lead SOIC package. Ordering information and package options (Pb‑free) are also listed.
| Controlled Supplies | +5V, +3.3V, +12V, -12V |
|---|---|
| Supply Current | 5.8 mA |
| Operating Temperature Range | 0 °C to 70 °C |
It controls four independent supplies: +5 V, +3.3 V, +12 V, and -12 V.
Pin 2 (FLTN) is the fault output; it is a 5 V CMOS output that is active low.
The device is supplied in a 16‑lead Small Outline Plastic (SOIC) package.
