Introduction
The HIP1011 was the first device designed to be fully
compatible with the PCI Hot Plug specification. This device
facilitates “HOT PLUGGING”, the removal or insertion of PCI
compliant cards without the need to power down the server
voltage bus. The HIP1011 controls all four (-12V, +12V, +3.3V,
+5V) supplies found in PCI applications, monitoring and
protecting against over current (OC) and under voltage (UV)
conditions. Reference the HIP1011 data sheet (4311) and the
PCI Hot Plug specification available from www.pcisig.com.
Figure 2 illustrates the typical implementation of the
HIP1011. Additional components for optimizing performance
in particular applications, ambient electrical noise levels or
desired features will be necessary.
The ease of implementation of the HIP1011 Hot Plug
Solution (HIP1011 and as few as 2 N-Channel MOSFETs
like the ITF86130 UltraFET) is complemented by the small
PCB foot print necessary, since both are available in 0.150
inch SOICs. The typical application requires only 1.1 sq.
inches of PCB board space (see Figure 1).
Key Feature Description and Operation
The HIP1011, two power MOSFETs and a few passive
components as configured in Figure 2, create a small and
simple yet complete power control solution. It provides the
maximum specified current for each supply to the PCI
adapter slot. Over current monitoring and protection for the
3.3V and 5V supplies is provided by sensing the voltage
across external current-sense resistors. For the +12V and
-12V inputs, over current protection is provided internally.
On-chip references are used to monitor the +5V, +3.3V and
+12V outputs for under voltage conditions. During an over
current condition on any output, or an under voltage
condition on the +5V, +3.3V or +12V outputs, all MOSFETs
are immediately latched-off and a LOW (0V) is presented to
the FLTN output. During initial power-up of the main V CC
supply (+12V), the PWRON input is inhibited from turning
on the switches, and the latch is held in the reset state until
the V CC input is greater than 10V. If FLTN is latched low
and PWRON is cycled low then high, the FLTN latch will
clear. User programing of the over current threshold by a
resistor connected to the OCSET pin and turn-on slew rate
by capacitors connected to the gate pins is provided.
