1 / 20 page 1 LTC4210-1/LTC4210-2 421012f APPLICATIO S DESCRIPTIO FEATURES TYPICAL APPLICATIO The LTC ®4210 is a 6-pin SOT-23 Hot SwapTM controller that allows a board to be safely inserted and removed from a live backplane. An internal high side switch driver controls the GATE of an external N-channel MOSFET for a supply voltage ranging from 2.7V to 16.5V. The LTC4210 provides the initial timing cycle and allows the GATE to be ramped up at an adjustable rate. The LTC4210 features a fast current limit loop providing active current limiting together with a circuit breaker timer. The signal at the ON pin turns the part on and off and is also used for the reset function. This part is available in two options: the LTC4210-1 for automatic retry on overcurrent fault and the LTC4210-2 for latch off on an overcurrent fault. s Allows Safe Board Insertion and Removal from a Live Backplane s Adjustable Analog Current Limit with Circuit Breaker s Fast Response Limits Peak Fault Current s Automatic Retry or Latch Off On Current Fault s Adjustable Supply Voltage Power-Up Rate s High Side Drive for External MOSFET Switch s Controls Supply Voltages from 2.7V to 16.5V s Undervoltage Lockout s Adjustable Overvoltage Protection s Low Profile (1mm) SOT-23 (ThinSOT TM) Package s Hot Board Insertion s Electronic Circuit Breaker s Industrial High Side Switch/Circuit Breaker Hot Swap Controller in 6-Lead SOT-23 Package , LTC and LT are registered trademarks of Linear Technology Corporation.
