MD1813

General Description

The Supertex 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 1.8 to 5.0V amplitude. 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. As an example, the input logic levels

may be 0 and 1.8V, the control logic may be powered by +5.0 and -

5.0V, and the output L and H levels may be varied anywhere over the

range of -5.0 to +5.0V. The output stage is capable of peak currents

of up to ±2.0 amps, depending on the supply voltages used and load

capacitance. 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 output high and the B output low. This assists

in properly pre-charging the coupling capacitors that may be used

in series in the gate drive circuit of an external PMOS and NMOS. A

built-in level shifter is for PMOS gate negative bias driving. It enables

the user-deﬁned damping control to generate return-to-zero bipolar

output pulses. The MD1813 has a non-inverting driver OUTD for

easy logic.
