intersil ISL6119 Manual
Update: 01 October, 2023
ISL6119 is a USB dual port power controller from Intersil that provides fully independent overcurrent (OC) fault protection. This device operates over the +2.5V to +5.5V range and features internal current monitoring, accurate current limiting, integrated power switches and current limited delay to latch-off for system protection. The ISL6119 current sense and limiting circuitry sets the current limit to a nominal 1A, making this device well suited for the USB port power management application. The ISL6119 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. 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 ISL6119 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 function to prevent current overshoot.
