Supertex MD1813

MD1813 is a high-speed quad MOSFET driver. It is designed to drive two N and two P-channel, high voltage, DMOS FETs for medical ultrasound applications, but may be used in any application that needs a high output current for a capacitive load. The input stage of the MD1813 is a high-speed level translator that is able to operate from logic input signals of 1.2 to 5.0 volt amplitude.

GENERAL DESCRIPTION

The Supertex MD1813 is a high-speed quad MOSFET driver. An adaptive threshold circuit is used to set the level translator threshold to the average of the input logic 0 and logic 1 levels. The level translator uses a proprietary circuit, which provides DC coupling together with high-speed operation. The output stage of the MD1813 has separate power connections, enabling the output signal L and H levels to be chosen independently from the driver supply voltages.
