HV / HF Dual Analog Switch for Industrial Applications
IXYS Integrated Circuits Division (ICD), Inc., a wholly owned subsidiary of IXYS Corporation, announced the introduction of the CPC7512, a dual shunt-isolated 1-form-A high-voltage, high-frequency analog switch that builds upon IXYS Integrated Circuits Division's design and fabrication expertise for industrial applications. This monolithic solid state device provides the switching functionality of two normally open (1-Form-A) solid state relays (SSRs) for high frequency applications in a small package. Both switches incorporate a T-switch compensation technique to provide 60dB of off-isolation at 1MHz by minimizing open state capacitive coupling.
Designed to provide flexible single ended or differential access to high voltage networks, the CPC7512 is configured as two independent switches with optimized state control. The self-biasing switches do not require external high voltage supplies for proper operation. A single 5V power supply provides sufficient biasing for enabling high voltage, bidirectional switching.
An integrated thermal shutdown feature provides not only enhanced protection for devices connected to high voltage networks up to +/-320V, but also an external signal to indicate the device is in thermal shutdown.
Applications for this highly reliable device include multiplexed ultrasonic transducer switching, battery monitoring and charging, automatic test equipment (ATE), instrumentation, industrial controls and monitoring. The versatile device may also be configured as a dual SPDT 1-Form-C switch by utilizing the shunt switch for driving two independent loads. The CPC7512 is offered in a 20-Pin SOIC package.
