MD1716, paired with TC8020, forms a three channel, three 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, Non-Destructive Testing (NDT), and piezoelectric transducer drivers. The MD1716 is a three channel logic controller circuit with 12 low impedance MOSFET gate drivers. There are three sets of control logic inputs, one each for channels A, B and C. Each channel consists of two pairs of MOSFET gate drivers. These drivers are designed to match the gate driving requirements of TC8020. The TC8020 is the high voltage output stage of the pulser. It consists of six pairs of MOSFETs. Each pair has both an N- and P-channel MOSFET. They are designed to have the same impedance and can provide typical peak currents of ±3.5 amps.
Additional Features
Advanced CMOS technology
4.5 to 12.5V power supply voltage
2.0A output source and sink current
6.5ns rise and fall time with 1.0nF load
10ns propagation delay
±2ns matched delay times
12 matched channels
1.8 to 3.3V CMOS logic interface
Smart logic threshold
Low inductance package
