Negative Voltage Hot Plug Controller
ISL6140, ISL6150
The ISL6140 is an 8 Ld, negative voltage hot plug
controller that allows 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
undervoltage threshold, or greater than the overvoltage
threshold. A programmable electronic circuit breaker
protects the system against shorts. The active low
PWRGD signal can be used to directly enable a power
module (with a low enable input)
The ISL6150 is the same part, but with an active high
PWRGD signal.
