The NIS5102 is a controller/FET IC that saves design time and reduces the number of components required for a complete hot swap application. It is designed for +12 V applications.
This chip includes a time delay for sequencing applications. It has a dual function OVLO pin that allows multiple units to be ganged together for simultaneous turn-on and shutdown, allowing units to be operated in parallel. It allows for user selectable undervoltage and overvoltage lockout levels. Its unique current limit circuit allows for adjustable current limit levels with no external power resistor. An internal temperature limiting circuit greatly increases the reliability of this device.
