MD1812
High-Speed Quad-MOSFET Driver
Features General Description The MD1812 is a high-speed quad-MOSFET driver
designed to drive two P-channel and two N-channel
high-voltage MOSFETs for medical ultrasound
applications and other applications requiring a
high-output current for a capacitive load. The input
stage of the MD1812 is a high-speed level translator
that is able to operate from logic input signals of 1.8V
to 5V amplitude. 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
level translator uses a proprietary circuit which
provides DC coupling together with high-speed
operation. 6 ns Rise and Fall Time
