Description
This monolithic, high-voltage, high-speed pulser generator features four independent
channels. It is designed for medical ultrasound imaging applications, but can also be used
to drive piezoelectric, capacitive or MEMS based transducers.
The STHV748S is composed of a controller logic interface circuit, level translators,
MOSFET gate drivers, noise blocking diodes, and high-power P-channel and N-channel
MOSFETs as the output stage for each channel. It also includes clamping-to-ground
circuitry, anti-leakage, anti-memory effect block, thermal sensor, and a T/R switch which
guarantees effective decoupling during the transmission phase. The STHV748S also
includes self-biasing and thermal shutdown blocks.
Each channel can support up to five active output levels with two half bridges. The output
stage of each channel is able to provide ±2 A peak output current. In order to reduce power
dissipation during continuous wave mode, a dedicated half-bridge is available and the peak
current is limited to 0.6 A.
An ESD reinforced structure was developed to prevent high voltage overshoots and inrush
current due to cabled transducer reflections. Each HV output is supported by a dedicate HV
diode network to withstand possible reflections, mitigating excessive voltage overshoot that
could lead to device damage.
Applications
Medical ultrasound imaging
Pulse waveform generators
NDT ultrasound transmission
Piezoelectric transducer drivers
