STMicroelectronics enters Ultrasound Market with STHV1600

To tap medical and industrial applications, STMicroelectronics has launched a new high-voltage, compact and cost-effective transmission pulser solution. STHV1600, is built using ST’s proven BCD8s-SOI technology that supports analog (Bipolar), digital (CMOS), and power (DMOS) circuits on the same die.
The STHV1600 provides a valuable solution for high-end cart systems and ultra-portable ultrasound equipment, while reinforcing ST’s existing portfolio of 4- and 8-channel pulser transmitters for medical and industrial ultrasound applications. To assure the smallest size, the state-of-the-art STHV1600 transmission (TX) pulser integrates high-resolution beamforming for its 16 independent channels.

STM Chips uniquely integrate beamforming and, with 16 channels, a high-voltage stage, and internal memory they offer the flexibility to address multiple platforms.

Offering the capability to program code excitation, it allows users to implement high voltage stages and store the patterns in memory. The STHV1600 includes several global blocks including thermal protection for the logic and for each channel, under-voltage protection, and self-biased high-voltage MOSFET gate drivers with internal checks. Moreover, the IC includes 65 kbits of embedded memory to store pattern-control settings.
The STHV1600 (in a 144-ball 10×10 TFBGA) is in production and currently sampling to lead customers. An evaluation board for it, STEVAL-IME014V1 is currently available to select customers.
