Update: 01 October, 2023
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 prevents the voltage bus from overcurrenting due to an OC event or short circuit, thus protecting the system and equipment.
