Negative Voltage Hot Plug Controller
The ISL6141 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. 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 600s before the circuit breaker shuts down the
FET. If the fault disappears before the 600s 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 current limit value. When
activated, the GATE is immediately turned off and then
slowly turned back on for a single retry (soft-start). The
active low PWRGD signal can be used to directly enable a
power module (with a low enable input). The ISL6151 is the
same device but has an active high PWRGD output.

Features
• Operates from -20V to -80V (-100V Absolute Max Rating)
• Programmable Inrush Current
• Programmable Over-Voltage Protection
• Programmable Under-Voltage Protection
- 135mV of hysteresis
- Equals ~4.6V of hysteresis at the power supply
• UVLO (Under-Voltage Lock-Out) ~ 16.5V
• Programmable Current Limit with 600s time-out
• IntelliTrip
TM
electronic circuit breaker distinguishes
between Over-Current and Hard Fault conditions
- Fast shutdown for Hard Faults with a single retry (fault
current > 4X current limit value).
• Pin Compatible with ISL6140/50.
• Power Good Control Output
- Monitors both the DRAIN (voltage drop across the FET)
and the GATE voltage; once both are OK, the Power
Good output is latched in the active state.
- PWRGD active high: ISL6151 (H version)
- PWRGD active low: ISL6141 (L version)
