General Description
The Supertex MD1711 is an IC for a two-channel, 5-
level, high voltage and high-speed transmitter driver. It
is
applications but can also be used for metal flaw
detection, nondestructive evaluation, and driving
piezoelectric transducers.
The MD1711 is a two-channel logic controller circuit
with low impedance MOSFET gate drivers. There are
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.
designed to match the drive requirements of the
Supertex TC6320. The MD1711 drives six TC6320s.
Each pair an N-channel and a P-channel MOSFET.
They are designed to have the same impedance and
can provide peak currents of over 2.0 amps
