General Description
The Supertex MD1712 is a two-channel, five-level, high
voltage and high speed transmitter driver IC. It is designed
for medical ultrasound imaging applications, but can also be
used for metal flaw detection, Non-Destructive Testing (NDT),
and for driving piezoelectric transducers.
The MD1712 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.
These drivers are designed to match the drive requirements of
the Supertex TC6320. The MD1712 drives six TC6320s. Each
pair consists of 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.
