Advance Information
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 volt 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.
