MD1716

Three Channel, Three Level, High Speed

Ultrasound Driver IC

Features

General Description

► Advanced CMOS technology

► 4.5 to 12.5V power supply voltage

► 2.0A output source and sink current

► 6.5ns rise and fall time with 1.0nF load

► 10ns propagation delay

The Supertex MD1716, paired with the Supertex TC8020,

forms a three channel, three level, high voltage, high speed,

transmit pulser chip set. The chip set is designed for medical

ultrasound imaging applications but can also be used for

metal ﬂaw detection, Non-Destructive Testing (NDT), and

piezoelectric transducer drivers.

► ±2ns matched delay times

► 12 matched channels

The MD1716 is a three channel logic controller circuit with 12

low impedance MOSFET gate drivers. There are three sets of

control logic inputs, one each for channels A, B and C. Each

channel consists of two pairs of MOSFET gate drivers. These

drivers are designed to match the gate driving requirements

of the Supertex TC8020.

► 1.8 to 3.3V CMOS logic interface

► Smart logic threshold

► Low inductance package

Applications

► Medical ultrasound imaging

► Piezoelectric transducer drivers

► Metal ﬂaw detection

The TC8020 is the high voltage output stage of the pulser.

It consists of six pairs of MOSFETs. Each pair has both an

N- and P-channel MOSFET. They are designed to have the

same impedance and can provide typical peak currents of

±3.5 amps.

► Non-Destructive Testing (NDT)
