Initial Release

High Speed Quad MOSFET Driver

General Description

Features

The Supertex MD1811 is a high speed, quad MOSFET driver designed to

drive high voltage P/N-channel MOSFETs for medical ultrasound applications

and other applications requiring a high output current for a capacitive load.

The high-speed input stage of the MD1811 can operate from a 1.2 to 5.0

volt logic interface with an optimum operating input signal range of 1.8 to 3.3

volts. An adaptive threshold circuit is used to set the level translator switch

threshold to the average of the input logic 0 and logic 1 levels. The input

logic levels may be ground referenced, even though the driver is putting

out bipolar signals. The level translator uses a proprietary circuit, which

provides DC coupling together with high-speed operation.

6ns rise and fall time

2 A peak output source/sink current

1.2V to 5V input CMOS compatible

5V to 12V total supply voltage

Smart Logic threshold

Low jitter design

Quad matched channels

Drives two N and two P Channel MOSFETs

Outputs can swing below ground

Low inductance quad ﬂat no-lead package

High-performance thermally-enhanced

The output stage of the MD1811 has separate power connections enabling

the output signal L and H levels to be chosen independently from the supply

voltages used for the majority of the circuit. As an example, the input logic

levels may be 0 and 1.8 volts, the control logic may be powered by +5 and

–5 volts, and the output L and H levels may be varied anywhere over the

range of –5 to +5 volts. The output stage is capable of peak currents of up

to 2 amps, depending on the supply voltages used and load capacitance

present. The OE pin serves a dual purpose. First, its logic H level is used

to compute the threshold voltage level for the channel input level translators.

Secondly, when OE is low, the outputs are disabled, with the A & C output

high and the B & D output low. This assists in properly pre-charging the AC

coupling capacitors that may be used in series in the gate drive circuit of an

external PMOS and NMOS transistor pair.
