Sunnyvale, Calif. - Supertex Inc. has introduced a high-speed, four-channel MOSFET driver for medical ultrasound imaging applications and other applications that require a high output current for a capacitive load. These MD1823 devices drive high voltage N- and P-channel MOSFETs.
A key feature of the MD1823 is a clock input pin that helps realign the input control pins to a master clock signal, which helps minimize delay time errors and clock jitter. Supertex said a logic input pin (BPS) can be tied high for users who don't want to use the clock realignment feature (if BPS = 1, the clock and registers are ignored)."
Another feature of the MOSFET driver simplifies the PCB layout by reducing the FPGA I/O requirement by only using two input pins for the three level RTZ ultrasound pulser MOSFET gate driver.
"The MD1823 MOSFET driver allows for a much improved discrete ultrasound pulser design," said Jimes Lei, director of applications engineer for Supertex, in a statement. "The added clock input will minimize time delay errors and jitter to achieve a sharper image."
The MD1823 is available in a lead-free/RoHS compliant 16-lead 3x3 QFN package (MD1823K6-G).
Availability: Samples are available from stock. Lead time for production quantities is four to six weeks, ARO.
