ISL6118
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
3.3VAUX 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 80m
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.
