Device Overview

Summary

MD0100 is a high voltage, two terminal, bi-directional, current-limiting protection device. The two terminals are interchangeable. It is designed to protect a low noise receiver from the high voltage transmit pulses in ultrasound applications and is commonly referred to as a T/R (transmit and receive) switch. The MD0100 can be considered as a normally closed switch with a typical switching resistance of 15O that allows small signals to pass. Once the voltage drop across the two terminals exceeds a nominal value of ±2.0V, the device will start to turn off. In the off state, the MD0100 can withstand up to ±100V across its terminals. A small amount of current, typical of 200µA, is allowed to flow through. The applications for the MD0100 are not limited to just ultrasound. It can also be used for resettable fuses to protect power lines, output short circuit protection, and data acquisition. The MD0100 is available in the SOT-89 package as a single channel device for ease of assembly. It is also available in a 4.0x4.0mm 8-Lead DFN package as a two channel device for high density requirements.

MD0100DB1 Demo Board
MD0100DB1 Demo Board ( MD0100DB1 )

The MD0100DB1 demo board contains four MD0100DK6-G dual packages providing 8 T/R switches in the system. There are no other external components on the board.
This demo board replaces 8 discrete diode bridge protection circuits. The input of the MD0100DB1 is called TX which is connected to the output of the transmitter, and the output is called RX which is connected to the input of the...
