General Description
The MD1711 is a two-channel logic controller circuit
with low-impedance MOSFET gate drivers. It is
intended to be used with external FETs as a five-level
high-voltage and high-speed transmitter. The MD1711
is designed for medical ultrasound imaging
applications but can also be used for metal flaw
detection, NDT and for driving piezoelectric
transducers.
The MD1711 has two sets of control logic inputs, one
for Channel A and one for Channel B. Each channel
consists of three pairs of MOSFET gate drivers. These
drivers are designed to match the drive requirements of
the TC6320. One MD1711 drives six TC6320s. Each
driver consists of an N-channel and a P-channel
MOSFET. They are designed to have the same
impedance and can provide peak currents of 2 amps.
