ADM1070ART-REEL7

Hot Swap Controller 1CH -18V N-Channel Negative Voltage 6Pin SOT-23 T/R

Product Details

The ADM1070 -48 V hot swap controller is designed for central office applications. The space-saving SOT-23 package occupies just 25% of the board area of an 8 pin SOIC solution. The device utilizes a linear current control method and protects the supply from in-rush currents board insertion and short circuits board failure. The ADM1070 also provides protection during voltage steps associated with card re-seating. It current limits under all conditions.
