Renesas Electronics Corporation Hot Swap Controllers ISL6119LIB-T

The ISL6119LIB-T is a USB dual port power supply controller designed for efficient power management in USB applications. It operates within a voltage range of 2.5V to 5.5V and features integrated 80mOc N-channel MOSFET switches, allowing for low on-resistance and improved thermal performance. The device includes accurate current sensing with a nominal current limit of 1A, ensuring protection against overcurrent conditions. This controller incorporates a 12ms fault delay to latch-off, independent fault output signals for each channel, and an undervoltage lockout feature that prevents output activation until the input voltage exceeds 2.5V. The controlled turn-on ramp time helps mitigate inrush current, reducing voltage droop during startup. The ISL6119LIB-T is compatible with both 3.3V and 5V logic families, making it versatile for various applications. It is available in a Pb-free 8 lead SOIC package, suitable for automated assembly processes.
