Intersil Unveils Endura ISL6117/ISL6120 Controllers

Intersil Corp. (Milpitas, CA) announced its new Endura™ ISL6117 and ISL6120 low-voltage, hot-swap controllers that allow boards to be safely inserted and removed from live backplanes. The ISL6117 controls a 3.3V rail and the ISL6120 controls a 2.5V rail. Both ICs are targeted for use on server motherboards for low-voltage, hot-swap, power control and are offered in the space-saving, eight-lead, SOIC package.

The ISL6117 and ISL6120 controllers offer a feature set that includes under-voltage monitoring and "power-good" notification, programmable over-current detection and fault isolation, programmable current regulation, programmable current limit time to latch off, adjustable turn-on ramp for soft-start, and fast sub-microsecond response to a dead short. Although designed primarily for high-side switch control, both ICs can also be used in a low-side configuration for control of much higher voltage potentials such as –48V.

The ISL6117 and ISL6120 are available now. The price, based on 1,000-piece quantities for the ISL6117CB and ISL6120CB, is $1.50 each. Both ICs are eight-lead SOIC packages with a 0°C to +85°C temperature range.
