Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground.

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.

In the output stage there are two pairs of MOSFETs. Each pair consists of a P-channel and an N-channel MOSFET. HV732 are designed to have the same impedance, and can provide peak currents of over ±2 amps. The built-in MOSFET gate driver outputs swing 0 to 12V on P_DR and N_DR pins. The P-channel damp output swings 0 to 5V on the DMPO pin.
