Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry's smallest 18-V hot-swap controller with power limiting that protects server and telecom equipment from over-current, over-voltage or short circuit events. The TPS24720 controller with programmable FET safe operating area (SOA) protection comes in a 3-mm x 3-mm standard QFN package, increases system reliability and simplifies hot-swap design.

Power protection with current monitoring The controller minimizes in-rush current and protects the load and the FET from potentially damaging transients. The TPS24720's programmable current limiting feature allows it to control an external N-channel MOSFET and provide accurate current monitoring. In addition when programmed to a 25-mV current limit threshold, there is a 50-percent reduction in sense resistor power loss compared to competitive devices with the same accuracy. The TPS24720's analog current monitor can provide real-time current data to ultra-low-power MSP430™ microcontrollers and TI's UCD9081 power supply sequencer to monitor overall system operation.
