Eight-Channel, High Speed, ±60V, ±1.0A,

Ultrasound RTZ Pulser

Features

General Description

► HVCMOS technology for high performance

► High density integrated ultrasound transmitter

► 0 to ±60V output voltage

The Supertex HV7350 is an eight 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 image devices.

► ±1.0A source and sink current in pulse mode

► ±1.0A source and sink current in RTZ mode

► Up to 20MHz operating frequency

► Matched delay times

HV7350 consists of a controller logic interface circuit, level translators,

MOSFET gate drives, and high current power P-channel and N-channel

MOSFETs as the output stage for each channel.

► Optional clock re-alignment

► 3.3V CMOS logic interface and reference

► +3.3V low voltage supply for V_DD

► Built-in linear regulators for ﬂoating gate driver

► Built-in output drain diodes & bleed resistors

The output peak currents of each channel are guaranteed to be over

±1.0A with up to ±60V pulse swings as well as return-to-zero (RTZ)

mode. The gate drivers for the output MOSFETs are powered by built-in

linear 5.0V regulators referenced to V_PPand V_NN. This direct coupling

topology of the gate drivers not only saves four ﬂoating voltage supplies

or AC coupling capacitors per channel, but also makes the PCB layout

smaller and easier.

Application

► Portable medical ultrasound imaging

► Piezoelectric transducer drivers

► Pulse waveform generator

An input clock pin is available to realign all the logic input control lines to

a master clock. Precise logic timing is always essential in any ultrasound

systems.
