General Description
The Supertex MD1213 is a high speed, dual MOSFET driver. It is
designed to drive high voltage P and N-channel MOSFET transistors
for medical ultrasound and other applications requiring a high
output current for a capacitive load. The high-speed input stage of
the MD1213 can operate from 1.2V to 5.0V logic interface with an
optimum operating input signal range of 1.8V 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 MD1213 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 1.8volts, the control logic
may be powered by +5.0V and –5.0V, and the output L and H levels
may be varied anywhere over the range of –5.0V 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 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 AC coupling capacitors that may be used in series in the
gate drive circuit of an external PMOS and NMOS transistor pair.
