PRELIMINARY
Negative Voltage Hot Plug Controller
Features
• Low Side External NFET Switch
The ISL6140 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
• Operates from -10V to -80V (-100V absolute max rating)
or +10V to +80V (+100V absolute max rating)
• Programmable Inrush Current
N-channel pass transistor. The pass transistor is turned off if
the input voltage is less than the undervoltage threshold, or
greater than the overvoltage threshold. A programmable
electronic circuit breaker protects the system against shorts.
The active low PWRGD signal can be used to directly enable
a power module (with a low enable input)
• Programmable Electronic Circuit Breaker (Over-Current
shutdown)
• Programmable Overvoltage Protection
• Programmable Undervoltage Lockout
• Power Good Control Output
- PWRGD Active High: (H Version) ISL6150
- PWRGD active Low: (L Version) ISL6140
The ISL6150 is the same part, but with an active high
PWRGD signal.

NOTES:
Typical Application (RL and CL are the Load)
1. Intersil Lead-Free products employ special lead-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which is compatible with both SnPb and lead-
free soldering operations. Intersil Lead-Free products are MSL
classified at lead-free peak reflow temperatures that meet or
exceed the lead-free requirements of IPC/JEDEC J Std-020B.
