Product Introduction

Overview

The STHV800L is an octal, monolithic, high-voltage and high-speed pulse generator designed by STMicroelectronics. It is primarily intended for medical ultrasound applications but can also be used for other piezoelectric, capacitive, or MEMS transducers. The device integrates various components such as a controller logic interface, level translators, MOSFET gate drivers, noise blocking diodes, and high power P-channel and N-channel MOSFETs. Each channel features a dedicated bridge to reduce power dissipation and jitter, especially in continuous wave mode. The STHV800L also includes self-biasing circuitry, thermal protection, and an integrated TR-switch, ensuring low power consumption and strong decoupling during transmission phases.
