A family of dual-channel, high-speed MOSFET drivers provides as much as 2A of peak current while driving capacitive loads. The three-member TPS281x family from Texas Instruments operates over a 4 to 14V range and incorporates a voltage regulator that extends the operating voltage range to 40V. Applications include power supplies, motor drives, and automotive designs.

With 20-nsec maximum rise and fall times and 30-nsec maximum propagation delay, these devices facilitate efficient high-frequency operation. They can drive FETs with approximately 60W loads at the maximum rated peak-output current. Quiescent supply current is 5 µA. The TPS2811, TPS2812, and TPS2813 differ in output configuration, with dual inverting, dual noninverting, and one inverting/one noninverting drivers, respectively. Each device costs $0.60 (1000) and is available in eight-lead plastic DIP, SO, and TSSOP packages.
