Data Sheet
1.6 V to 16.5 V Hot Swap Controller with Soft Start ADM1170
FEATURES
Controls supply rails from 1.6 V to 16.5 V Supply voltage range from 2.7 V to 16.5 V Allows protected board removal and insertion to a live
backplane External sense resistor provides adjustable analog current
limit with circuit breaker Soft start controls inrush current profile Peak fault current limited with fast response Charge pumped gate drive for external N-FET switch Automatic retry or latch-off during current fault Undervoltage lockout 8-lead, TSOT package
APPLICATIONS
Hot swap board insertion: line cards, raid systems Industrial high-side switches/circuit breakers Electronic circuit breakers
GENERAL DESCRIPTION
The ADM1170 is a hot swap controller that safely enables a printed circuit board to be removed and inserted to a live backplane. This is achieved using an external N-channel power MOSFET with a current control loop that monitors the load current through a sense resistor. An internal charge...
