STMicroelectronics Introduces the STHV748, a Highly Integrated Low-Noise Ultrasound Pulse Controller
The STHV748 is a highly integrated low-noise ultrasound pulse controller that built using ST’s advanced high-voltage BCD mixed-signal technology. The STHV748 provides four independent channels, each of which generates precisely controlled high-voltage pulses to drive piezoelectric crystals or other transducers. The device enables the next generation of high-performance ultrasound imaging systems in a small form factor. The role of the STHV748 is to provide the accurately timed high-voltage pulses that generate the ultrasound burst and switch to receive mode to detect the echoed signals. By integrating the transmit/receive switch, the STHV748 minimizes the number of external components required in applications such as stationary and portable ultrasound scanners, allowing further miniaturization and cost reduction. The STHV748 integrates CMOS digital control logic, analog level translators, MOSFET gate drivers and high-power N- and P-channel MOSFET output stages in a fully self-biasing architecture…
