DATASHEET ISL6140, ISL6150 FN9039 Rev 5.00 Negative Voltage Hot Plug Controller December 3, 2015 The ISL6140 is an 8 Ld, negative voltage hot plug Features controller that allows a board to be safely inserted and Low Side External NFET Switch removed from a live backplane. Inrush current is Operates from -10V to -80V (-100V absolute max limited to a programmable value by controlling the rating) or +10V to +80V (+100V absolute max gate voltage of an external N-channel pass transistor. rating) The pass transistor is turned off if the input voltage is Programmable Inrush Current less than the undervoltage threshold, or greater than the overvoltage threshold. A programmable electronic Programmable Electronic Circuit Breaker circuit breaker protects the system against shorts. The (overcurrent shutdown) active low PWRGD signal can be used to directly enable Programmable Overvoltage Protection a power module (with a low enable input) Programmable Undervoltage Lockout The ISL6150 is the same part, but with an active high Power Good Control Output PWRGD signal. - PWRGD Active High: (H Version) ISL6150 - PWRGD active Low: (L Version) ISL6140 Pb-free available (RoHS compliant) Applications VoIP (Voice over Internet Protocol) Servers Telecom systems at -48V Negative Power Supply Control +24V Wireless Base Station Power Related Literature ISL6140/50EVAL1 Board Set, AN9967 ISL6116 Hot Plug Controller, FN9100 NOTE: See www.intersil.com/hotplug for more information.

Please refer to TB347 for details on reel specifications. 2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. 3.

Typically, an external pull-up of some kind is used to pull the pin PWRGD (ISL6140 L Version) Pin 1 high (many brick regulators have a pull-up function This digital output is an open-drain pull-down device. built in). The Power Good comparator looks at the DRAIN pin voltage compared to the internal VPG reference (VPG is PWRGD (ISL6150 H Version) Pin 1 nominal 1.7V) this essentially measures the voltage This digital output is a variation of an open-drain drop across the external FET and sense resistor. If the pull-down device. The power good comparator is the voltage drop is small (<1.7V is normal), the PWRGD same as described above, but the polarity of the output pin pulls low (to VEE) this can be used as an active is reversed, as follows: low enable for an external module.
