General Description
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.
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.
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.
