Data Sheet
Negative
Voltage Hot Plug Controller
The ISL6142/52 are 14 pin, negative
voltage hot plug controllers that allow a board to be safely inserted and removed from a live backplane.
Inrush current is limited to a programmable value by controlling the gate
voltage of an external N-channel pass transistor.
The pass transistor is turned off if the input
voltage is less than the Under-
Voltage threshold, or greater than the Over
Voltage threshold.
The PWRGD/PWRGD outputs can be used to directly enable a power module.
When the Gate and DRAIN
voltages are both considered good the output is latched in the active state.
