STMicroelectronics’ 64-channel high-voltage analog-switch IC delivers unprecedented integration for advanced ultrasound systems, probes, piezoelectric drivers, automated test equipment, industrial automation, and process-control systems.
The STHV64SW comprises a shift register for logic control signals, self-biased high-voltage MOSFET gate drivers, and N-channel MOSFET switches capable of providing up to ±3A peak output current. The switches respond quickly, with 1.5µs turn-on time, and low quiescent current saves power when turned off. Low on-resistance with low distortion and crosstalk ensure high signal integrity. Thermal shutdown and under-voltage lockout (UVLO) are built-in to ensure safe operation.
The STHV64SW can operate with various combinations of high-voltage supplies up to -100V/+100V, 0V/200V, or -200V/0V (more info).
