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.
The IntelliTrip
TM
electronic circuit breaker and programmable
current limit features protect the system against short circuits.
When the Over-Current threshold is exceeded, the output current
is limited for a time-out period before the circuit breaker trips and
shuts down the FET. The time-out period is programmable with an
external capacitor connected to the CT pin. If the fault disappears
before the programmed time-out, normal operation resumes. In
addition, the IntelliTrip
TM
electronic circuit breaker has a fast Hard
Fault shutdown, with a threshold set at 4 times the Over-Current
trip point. When activated, the GATE is immediately turned off and
then slowly turned back on for a single retry.
The IS+, IS-, and IS
OUT
pins combine to provide a load current
monitor feature that presents a scaled version of the load current
at the IS
OUT
pin. Current to voltage conversion is accomplished
by placing a resistor (R9) from IS
OUT
to the negative input (-48V).
