Low cost, high quality, and high performance with BCD8s-SOI technology
Beamforming integration, multi-platform processing flexibility
STMicroelectronics has launched the STHV1600, a new small, robust, and cost-effective high-voltage transfer pulser solution targeting key medical and industrial applications. This device is implemented using ST's proven BCD8s-SOI technology to support analog (bipolar), digital (CMOS), and power (DMOS) circuits on the same die.

The STHV1600 strengthens ST's existing portfolio of 4-channel and 8-channel pulser transmitters developed for medical and industrial ultrasound applications, while providing high-value solutions for high-end cart systems and ultra-compact portable ultrasound equipment.

The state-of-the-art STHV1600 transmission (TX) pulser incorporates high-resolution beamforming for 16 independent channels to ensure a minimum size. Additionally, since it is provided with the ability to program code excitation, users can implement high-voltage stages and store patterns in memory. Each channel can support up to 5 output levels to maximize flexibility, and the output stage can provide a peak output current of up to ±2A independently of the high-voltage power pin.

The STHV1600 includes several global blocks, including logic and thermal protection for each channel, under-voltage protection, and a self-biased high-voltage MOSFET gate driver with internal inspection capabilities. This IC has 65kbit of built-in memory to store pattern control settings.

The STHV1600 (144-ball 10x10 TFBGA package) is currently in production, and samples are being supplied to leading customers. The STEVAL-IME014V1 evaluation board for the STHV1600 is currently available as an option. For more information, please contact ST Korea or an authorized distributor.
