The ADM1070 also features single-pin undervoltage and over-  
voltage detection. The FET is turned off if a nontransient  
voltage less than the undervoltage threshold, typically –36 V, or  
greater than the overvoltage threshold, typically –77 V, is detected  
on the UV/OV Pin. The operating voltage window of the  
ADM1070 is programmable and is determined by the ratio R1/R2.  
GENERAL 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. The part achieves this by providing robust  
current limiting, protection against transient and nontransient  
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.  
Time filtering on the undervoltage and overvoltage detection  
and current limiting is programmable via the TIMER Pin. An  
external capacitor connected between the TIMER Pin and VEE  
determines the undervoltage/overvoltage time filter and the  
timeout in current limit. If the pin is tied to VEE, the time filter  
values and the current limit timeout revert to default figures.  
In-rush current is limited to a programmable value by control-  
ling the gate drive of an external N-channel FET. The current  
limit can be controlled by the choice of the sense resistor,  
RSENSE. Added control of the in-rush current is provided by an  
on-chip timer that uses pulsewidth modulation to allow the  
maximum current to flow for only 3% of the time. An autorestart  
occurs after a current limit timeout. After seven successive  
autorestarts, the fault will be latched and the part goes into  
shutdown with the result that the external FET is disabled until  
the power is reset.  
The ADM1070 is fabricated using BiCMOS technology for mini-  
mal power consumption. The part is available in a small  
6-Lead SOT-23 package.
