General Description
The Supertex MD1820 is a high speed, four channel MOSFET driver
designed to drive high voltage P- and 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 MD1820
can operate from a 1.8 to 5.0V logic interface with an optimum operating
input signal range of 1.8 to 3.3V. 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.
The output stage of the MD1820 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 1.8V, 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 ±2.0A, depending on the
supply voltages used and load capacitance present. The PE pin serves
a dual purpose. First, its logic H level is used to compute the threshold
voltage level for the channel input level translators. Second, when PE
is low, the outputs are HiZ. This assists in properly precharging the AC
coupling capacitors that may be used in series in the gate drive circuit
of an external PMOS and NMOS transistor pair.
