Device Overview

Summary

MD1715, paired with TC8020, forms a two channel, five 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 MD1715 is a two channel logic controller circuit with 12 low impedance MOSFET gate drivers. There are two sets of control logic inputs, one each for channels A and B. Each channel consists of three pairs of MOSFET gate drivers. These drivers are designed to match the drive requirements of TC8020. The TC8020 is the output stage of the pulser, with six pairs of MOSFETs. Each pair consists of a P-channel and an N-channel MOSFET. They are designed to have the same impedance and can provide typical peak currents of ±3.5A at 200V.
