High-voltage 64-channel switch IC can deliver ±3A peak current

New Products |
STMicroelectronics’ 64-channel high-voltage analog-switch IC, 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. ST has created this advanced device leveraging proprietary BCD6s-SOI (silicon on insulator) and BCD8s SOI process technologies to combine precise analog circuitry (Bipolar), low-voltage CMOS logic, and robust DMOS power stages on the same chip. The STHV64SW can operate with various combinations of high-voltage supplies up to -100V/+100V, 0V/200V, or -200V/0V. The highly integrated 64-channel analog-switch IC comes in a small FCBGA package as does the recently announced companion 16-pulser STHV1600 IC, enabling system manufacturers to increase channel density for superior ultrasound image resolution, using minimal board space.
