The Supertex MD1711 is an IC for a two-channel, 5- level, high voltage and high-speed transmitter driver. It is designed for medical ultrasound imaging applications but can also be used for metal flaw detection, nondestructive evaluation, and driving piezoelectric transducers.
The MD1711 is a two-channel logic controller circuit with low impedance MOSFET gate drivers. There are two sets of control logic inputs, one for channel A and one for Channel B. Each channel consists of three pairs of MOSFET gate drivers. These drivers are designed to match the drive requirements of the Supertex TC6320. The MD1711 drives six TC6320s. Each pair an N-channel and a P-channel MOSFET. They are designed to have the same impedance and can provide peak currents of over 2.0 amps.
