The Supertex HV732 is a single, complete, high-voltage, high-speed, ultrasound transmitter pulser. It is designed for medical ultrasound imaging applications. The HV732 has built-in damping for faster RTZ waveform capability and high voltage MOSFET gate-clamping function for quick ramping of the output voltage amplitude. The HV732 consists of a control logic circuit, level translators, MOSFET gate drive buffers, clamp circuits, and high current, high voltage MOSFETs as the ultrasound transmitter pulser output stage.
