ISL6142 - Negative Voltage Hot Plug Controller

Datasheet Summary

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 IntelliTripTM electronic circuit breaker has a fast Hard Fault shutdown, with a threshold set at 4 times the Over-Cu.

ISL6142, ISL6152 ® 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 OverVoltage 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 IntelliTripTM electronic circuit breaker and programmable current limit features protect the system against short circuits.
