ISL6119
USB Dual Port Power Supply Controller
The ISL6119 is a USB dual port power controller, fully independent overcurrent (OC) fault protection IC. Operational over the +2.5V to +5.5V range, this device 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.
