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 1.2 to 5.0 volt 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 0V and 1.8V, the control logic may be powered by +5V and –5V, and
the output L and H levels may be varied anywhere over the range of –5V
to +5V. The output stage is capable of peak currents of up to ±2 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 OUT
