Four Channel, High Speed ±70V 2.0A

Ultrasound RTZ Pulser

Features

General Description

► HVCMOS technology for high performance

► High density integrated ultrasound transmitter

► 0 to ±70V output voltage

The Supertex HV7331 is a four-channel, monolithic, high voltage,

high speed pulse generator with built in fast return to zero damping

FETs. This high voltage and high-speed integrated circuit is

designed for portable medical ultrasound imaging devices, and can

also be used for NDT applications.

► ±2.0A source and sink minimum pulse current

► Up to 20MHz operation frequency

► ±2.5ns matched delay times

► 2.5 to 5.0V CMOS logic interface

► Built-in output drain diode and bleed resistors

► CW/RTZ Doppler quick switching

► Two damping mode options

The HV7331 consists of a controller logic interface circuit, level

translators, MOSFETgatedrives, andhighcurrentpowerP-channel

and N-channel MOSFETs as the output stage for each channel.

The peak output currents of each channel are guaranteed to be

over 2.0A with up to a ±70V pulse swing. The integrated regulators

for the gate drivers not only saves two ﬂoating voltage supplies, but

also makes the PCB layout easier. The split common source for

the P or N damping MOSFETs provide pulse or CW Doppler mode

quick switch-over for cost and power savings.

Applications

► Portable medical ultrasound imaging

► Piezoelectric transducer drivers

► NDT ultrasound transmission

► Pulse waveform generator
