Device Overview

Summary

MD1712 is a two-channel, five-level, high voltage and high speed transmitter driver IC. It is designed for medical ultrasound imaging applications, but can also be used for metal flaw detection, Non-Destructive Testing (NDT), and for driving piezoelectric transducers. The MD1712 is a two-channel logic controller circuit with low impedance MOSFET gate drivers. There are two sets of control logic inputs, one for channel A and one for channel B. Each channel consists of three pairs of MOSFET gate drivers. These drivers are designed to match the drive requirements of TC6320. The MD1712 drives six TC6320s. Each pair consists of an N-channel and a P-channel MOSFET. They are designed to have the same impedance and can provide peak currents of over 2.0amps.
