Description Packing
Tray The STHV64SW is an integrated circuit which features 64 independent switches. 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.
