Negative Voltage Hot Plug Controller ISL6140, ISL6150 The ISL6140 is an 8 Ld, 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 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) The ISL6150 is the same part, but with an active high PWRGD signal. Features • Low Side External NFET Switch • Operates from -10V to -80V (-100V absolute max rating) or +10V to +80V (+100V absolute max rating) • Programmable Inrush Current • Programmable Electronic Circuit Breaker (overcurrent shutdown) • Programmable Overvoltage Protection • Programmable Undervoltage Lockout • Power Good Control Output - 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.
