It is designed for medical ultrasound applications, but can also be used for driving piezoelectric, capacitive or MEMS transducers, and in industrial application such as generic high voltage switches. The STHV64SW comprises a shift register for serial communication, self-biased high voltage MOSFET gate drivers, high power N-channel MOSFETs, bleed resistance for each switch, thermal sensor and undervoltage lockout. Moreover, the STHV64SW includes self-biasing and thermal shutdown blocks. The switches are capable of providing up to ±3 A peak output current.
