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 1.8 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 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 1.8V, the control logic may be powered by
+5.0 to -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 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.
