Texas Instruments High-Performance Analog UCD7138DRST

The UCD7138DRST is a 4-A source and 6-A sink single-channel synchronous-rectifier MOSFET driver with body-diode conduction sensing and reporting, designed for use with Texas Instruments UCD3138A digital power controllers. It operates from a 4.5-V to 18-V supply, features a 14-ns typical propagation delay and 5-ns rise and fall times, and supports frequencies up to 2 MHz. The device is housed in a 6-pin 3-mm × 3-mm WSON package with an exposed thermal pad for enhanced thermal performance. It includes a -150-mV threshold body-diode conduction detection circuit capable of sensing conduction times as low as 10 ns and offers gate turn-on edge optimization. Operating temperature range is -40°C to 125°C.
