It is designed to drive high-voltage P-channel and N-channel MOSFETs 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 1.8V to 5V 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 0V and 1.8V, the control logic may be powered by +5V to - 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 ±2A, 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 pute the threshold voltage level for the channel input level translators. Second, when OE is low, the outputs are disabled with the A output high and the B output low. This...
