General Description

The MD1716, paired with Microchip’s TC8020, forms a

3-channel 3-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, NDT, and piezoelectric

transducer drivers.

The MD1716 is a 3-channel logic controller circuit with

12 low-impedance MOSFET gate drivers. There are

three sets of control logic inputs—one for Channel A,

one for Channel B, and one for Channel C. Each

channel consists of two pairs of MOSFET gate drivers.

These drivers are designed to match the drive

requirements of Microchip’s TC8020.

The TC8020 is the high-voltage 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.
