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
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
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
current monitor feature that presents a scaled version of
the load current at the IS
conversion is accomplished by placing a resistor (R9) from
IS
