LTC2956 Micropower, Reverse Battery Protected Pushbutton Controller and Sleep Timer with Hot-Swap Controller

Mar 19th 2015
The LTC®2956 is a micropower, wide input voltage range, configurable wake-up timer with pushbutton control. It periodically wakes up and turns on a connected system to perform tasks like monitoring temperature or capturing images. After completing the task, the LTC2956 turns the system off to conserve power. ...

LTC4226 Parallel MOSFETs in Hot Swap Circuits

Dan Eddleman - Senior Applications Engineer
Gabino Alonso - Strategic Marketing Engineer
Mar 13th 2015
The Good, the Bad, and the Ugly Introduction While it is often desirable, and sometimes absolutely critical, to use multiple parallel MOSFETs in Hot Swap™ circuits, careful analysis of Safe Operating Area (SOA) is essential. Each additional parallel MOSFET added to a circuit improves the voltage drop, power loss, and ...

LTC4252B-1 –48V/2.5A Hot Swap Controller

Sep 2nd 2014
The LTC®4252 negative voltage Hot SwapTM controller allows a board to be safely inserted and removed from a live backplane. Output current is controlled by three stages of current limiting: a timed circuit breaker, active current limiting and a fast feedforward path that limits peak current under worst-case catastrophic ...

LTC4364-1 4A, 12V Overvoltage Output Regulator with Ideal Diode Withstands 200V 1ms Transient at VIN

Aug 4th 2014
The LTC4364 surge stopper with ideal diode controller protects loads from high voltage transients. It limits and regulates the output during an overvoltage event, such as load dump in automobiles, by controlling the voltage drop across an external N-channel MOSFET pass device. The LTC4364 also includes a timed, current limited ...
