Analog Devices Inc. ADM1070ARTZ-REEL7

Description
The ADM1070 is a negative voltage hot swap controller that allows a board to be safely inserted and removed from a live -48 V backplane. It provides robust current limiting, protection against transient and non-transient short circuits, and overvoltage and undervoltage conditions. The ADM1070 typically operates from a negative voltage of up to -80 V and can tolerate transient voltages of up to -200 V.

Features
Allows safe board insertion and removal from a live -48 V backplane
Typically operates from -36 V to -80 V
Tolerates transients up to -200 V (limited by external components)
Accurate programmable linear current limit for in-rush control and short circuit protection
Programmable timeout in current limit
Limited consecutive retry: auto-restart after current limit timeout
Shutdown after seven consecutive auto restarts
Provides immunity from step induced current spikes
Default timing provided with no TIMER capacitor
Single pin undervoltage/overvoltage detection
Programmable operating voltage window
Programmable undervoltage/overvoltage time filter
Small 6-Lead SOT-23 package
