Keywords:MOSFET driver? medical ultrasound application? high resolution imaging?

Supertex Inc. has launched a logic controller with twelve low impedance MOSFET gate drivers. The MD1716 forms a three-channel, three-level, high-voltage, high-speed, transmit pulser chipset when paired with a complementary MOSFET array, such as the Supertex TC8020.

MD1716 has two separate gate drive voltage controls to minimize power consumption. It generates a three-level waveform that is ideal for CW, PW and color Doppler for high-resolution imaging in medical ultrasound applications. The IC has 2ns matched delay times, a 10ns propagation delay and a 6.5ns rise and fall time with a 1nF load.

The RoHS-compliant MD1716 is available in a 40-lead QFN package (MD1716K6-G). Samples are available with a lead-time of four to six weeks.
