General Description
The Supertex MD1210 is a high speed, dual MOSFET driver. It is
designed to drive high voltage N- and P-channel MOSFET
transistors for medical ultrasound applications and other
application requiring a high output current for a capacitive load.
The high-speed input stage of the MD1210 can operate from 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.
The output stage of the MD1210 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 +5.0 and –5.0 volts,
and the output L and H levels may be varied anywhere over the
range of –5.0 to +5.0 volts. The output stage is capable of peak
currents of up to ±2.0 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 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.
