MD1821  
High Speed, Four Channel MOSFET Driver  
with Inverting Outputs  
Features  
General Description  
► Inverting MOSFET driver  
The Supertex MD1821 is a high speed, four channel MOSFET driver  
designed to drive high voltage P- and 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 MD1821  
can operate from a 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.  
► 6.0ns rise and fall time  
► 2.0A peak output source/sink current  
► 1.8 to 5.0V input CMOS compatible  
► 5.0 to 10V total supply voltage  
► Smart logic threshold  
► Low jitter design  
► Four matched channels  
► Drives two P- and two N-channel MOSFETs  
► Outputs can swing below ground  
► Low inductance, quad flat no-lead package  
► High performance, thermally enhanced  
packaging  
The output stage of the MD1821 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 and -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 PE pin serves a dual  
purpose. First, its logic H level is used to compute the threshold voltage  
level for the channel input level translators. Second, when PE is low, the  
outputs are disabled, with the A & C output high and the B & D output  
low. This assists in properly precharging 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  
► Piezoelectric transducer drivers  
► Non-Destructive Testing (NDT)  
► PIN diode driver  
► CCD Clock driver/buffer  
► High speed level translator
