MD1820
High-Speed 4-Channel MOSFET Driver with Non-Inverting Outputs
Features General Description The MD1820 is a high-speed, 4-channel MOSFET
driver designed to drive high-voltage P-channel 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 MD1820 can operate from a
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. Non-inverting, 4-channel MOSFET Driver
