STMicroelectronics STHV748 Quad Ultrasound Pulser Datasheet
The STHV748 is a monolithic, high-voltage, high-speed pulser generator featuring four independent channels. It is designed for medical ultrasound imaging applications but can also drive other piezoelectric, capacitive, or MEMS-based transducers. The device includes embedded low-power, floating high-voltage drivers and supports mode operations such as 3/5-level output waveforms and continuous wave (CW) operations.
Key features include up to 20 MHz operating frequency, +2 A source and sink current per channel, and fully integrated clamping-to-ground functions. The chip utilizes HV MOS topology to minimize current consumption and includes self-biasing and thermal shutdown blocks. Each channel supports up to five active output levels with two half bridges.
