ISL6142 Datasheet Negative Voltage Hot Plug Controller

Manufacturer: Intersil (now Renesas)

Overview: 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.

Key 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.
