ST's monolithic, high-voltage, high-speed, highly-integrated ultrasound pulsers with T/R switch feature four or eight independent channels.
The ST proprietary BCD6s-SOI and BCD8s-SOI process technologies enable the combination of low-voltage CMOS logic, precise analog circuitry and robust power stages on the same chip, offering unprecedented level of integration.
The devices comprise, controller logic interface circuit, level translators, MOSFET gate drivers, noise blocking diodes and high-power P-channel and N-channel MOSFETs as output stage for each channel, clamping-to-ground circuitry, anti-leakage, anti-memory effect block, thermal sensor and lastly the integrated T/R switch which guarantees a strong decoupling during transmission phase.
