The ISL6140 is an 8-pin, 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 Under-Voltage threshold, or
greater than the Over-Voltage 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.
The ISL6141/51 are pin compatible with the ISL6140/50. In
addition to the features noted above these enhanced hot
plug controllers offer programmable current limiting with a
600us time-out. When the Over-Current threshold is
exceeded, the output current is limited for 600µs before the
circuit breaker shuts down the FET. If the fault disappears
before the 600µs time-out, normal operation resumes.The
new IntelliTrip
Fault shutdown with a threshold set at 4 times the current
limit value. When activated, the GATE is immediately turned
off and then slowly turned back on for a single retry (soft-
start). The GATE and DRAIN voltages are both monitored
with separate comparators to enable the Power Good output
at start-up. When the DRAIN and GATE voltage conditions
are met, the comparators trip and latch the
PWRGD/PWRGD output into the active state. At this point
any of the signals that turn off the gate will reset the latch
and drive the PWRGD/PWRGD output inactive.
