SMART HotPlugt IC/Inrush

Limiter/Circuit Breaker

The SMART HotPlug Integrated Circuit combines the control

function and power FET into a single IC that saves design time and

reduces the number of components required for a complete hot swap

application. It is designed to allow safe insertion and removal of

electronic equipment to −48 V backplanes. This chip features

simplicity of use combined with an integrated solution.

The SMART HotPlug includes user selectable undervoltage and

overvoltage lockout levels. It also has adjustable current limiting that

can be reduced from the maximum level with a single resistor.

Operation at the maximum current level requires no extra external

components. An internal temperature shutdown circuit greatly

increases the reliability of this device.
