MD1811  
Initial Release  
High Speed Quad MOSFET Driver  
General Description  
Features  
The Supertex MD1811 is a high speed, quad MOSFET driver designed to  
drive high voltage P/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 MD1811 can operate from a 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.  
6ns rise and fall time  
2 A peak output source/sink current  
1.2V to 5V input CMOS compatible  
5V to 12V total supply voltage  
Smart Logic threshold  
Low jitter design  
Quad matched channels  
Drives two N and two P Channel MOSFETs  
Outputs can swing below ground  
Low inductance quad flat no-lead package  
High-performance thermally-enhanced  
The output stage of the MD1811 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 and  
–5 volts, and the output L and H levels may be varied anywhere over the  
range of –5 to +5 volts. The output stage is capable of peak currents of up  
to 2 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 & C output  
high and the B & D 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.  
Applications  
Medical ultrasound imaging
