Dual Power Supply Controller

The ISL6118 is a dual channel, fully independent overcurrent

(OC) fault protection IC for the +2.5V to +5.5V environment.

This device features internal current monitoring, accurate

current limiting, integrated power switches and current

limited delay to latch-off for system protection.

The ISL6118 current sense and limiting circuitry sets the

current limit to a nominal 0.6A, which is well suited for the

3.3V AUX ACPI application. The ISL6118 is the ideal

companion chip to the HIP1011D and HIP1011E dual PCI

hot plug controllers. Together these and the ISL6118 fully

control the four legacy PCI voltages (±12V, +3.3V, +5V) and

the 3.3V AUX, respectively, for power control of two PCI

slots compliant to PCI Bus Power Management Interface

Spec Rev 1.1. Designed to be co-located with the HIP1011D

on the motherboard, the ISL6118 provides OC fault

notification, accurate current limiting and a consistent timed

latch-off thus isolating and protecting the voltage bus in the

presence of an OC event or short circuit during all PCI Bus

Power States as defined by the PCI specification. The 12ms

time to latch-off is independent of the adjoining switch’s

electrical or thermal condition and the OC response time is

inversely related to the OC magnitude.

Each ISL6118 incorporates in a single 8-lead SOIC

package two 80mΩ N-channel MOSFET power switches

for power control. Each switch is driven by a constant

current source giving a controlled ramp up of the output

voltage. This provides a soft start turn-on eliminating bus

voltage drooping caused by inrush current while charging

heavy load capacitances. Independent enabling inputs and

fault reporting outputs for each channel are compatible with

3V and 5V logic to allow external control and monitoring.

The ISL6118 undervoltage (UV) feature prevents turn-on of

the outputs unless the correct ENABLE state and

VIN > 2.5V are present. During initial turn-on the ISL6118

prevents fault reporting by blanking the fault signal. Rising

and falling outputs are current-limited voltage ramps so that

both the inrush current and voltage slew rate are limited,

independent of load. This reduces supply droop due to

surge and eliminates the need for external EMI filters.

During operation, once an OC condition is detected the

appropriate output is current limited for 12ms to allow

transient conditions to pass. If still in current limit after the

current limit period has elapsed, the output is latched off

and the fault is reported by pulling the corresponding

FAULT low. The FAULT signal is latched low until reset by

the ENABLE signal being de-asserted at which time the

FAULT signal will clear.
