MD1821
High-Speed 4-Channel MOSFET Driver with Inverting Outputs
Features General Description The MD1821 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 MD1821 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. Inverting MOSFET Driver
