MD1715
2-Channel 5-Level High-Speed Ultrasound Driver IC
Features General Description The MD1715, paired with Microchip’s TC8020, forms a
2-channel five-level high-voltage high-speed transmit
pulser chip set. The chip set is designed for medical
ultrasound imaging applications but can also be used
for metal flaw detection, NDT and piezoelectric
transducer drivers. Advanced CMOS Technology

Low-inductance Package The MD1715 is a 2-channel logic controller circuit with
12 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 Microchip’s TC8020. Applications The TC8020 is the output stage of the pulser, with six
pairs of MOSFETs. Each pair consists of a P-channel …
