High-speed drive of scanner piezoelectric transducer and achievement of minimum pulse duration of 5ns

STMicroelectronics (hereinafter ST) has launched a family of transmitters that can improve the performance and integration of next-generation high-performance scanners for medical and industrial applications.

ST announced on the 3rd that it has launched a family of 32-channel advanced ultrasonic transmitter models that support portable applications with high output current.

The new STHVUP32 transmitter provides ±800mA, supporting portable systems that require additional drive capabilities for coaxial cable-mounted probes.

The new 32-channel version added to the portfolio features similar capabilities to the 64-channel STHVUP64, and of.

These transmitter products support innovative features that maximize image quality, integrated digital beam steering, a space-saving driver architecture, and low power consumption.

In addition to the standard 3-level output, the STHVUP32 features a 5-level output function to optimize image quality more flexibly.

In addition, the high output current drives the scanner's piezoelectric transducer at high speed to support various imaging modes and helps achieve a minimum pulse duration of 5ns to enhance image detail.
<bThis transmitter supports continuous-wave (CW) and pulsed-wave (PW) operating modes, providing various types of analysis such as cavity and fluid flow.

Digital beam steering improves directional control capabilities by providing superior precision compared to conventional analog steering that uses delay circuits.

Since beam steering logic is integrated, there is no need to use companion chips such as FPGAs. This reduces PCB space and routing complexity, and avoids FPGA design issues.

In addition, the new transmitter features a self-biased driver architecture, eliminating the need to connect decoupling capacitors to the transmitter's power supply pins.

This reduces the circuit footprint and lowers the Bill of Materials (BoM). Since the STHVUP32 is available in a smaller package compared to ICs in its class, designers can also develop next-generation products with much smaller form factors.

STHVUP32 supports ultra-low power consumption, which is the core of battery-operated systems, while providing a wealth of features that deliver an excellent user experience.

It has built-in memory for storing transmission patterns and supports synchronization using a clock signal of up to 200 MHz, thereby minimizing jitter and improving image quality.

In addition, it incorporates protection functions such as noise blocking, thermal protection, undervoltage protection, and recirculating current protection, and provides a diagnostic register that can directly read the cause of an interrupt to facilitate debugging in the event of a malfunction.

STHVUP32 is currently being produced in an 11.5mm x 10.5mm x 1.35mm 168-ball FC-BGA168 package.
