CPC7232K

Overview

The CPC7232K is an eight-channel high-voltage analog switch manufactured by IXYS Integrated Circuits Division. It integrates built-in bleeder resistors to discharge stored charge in capacitive loads, ensuring rapid signal settling times. The device utilizes BCDMOS technology for robust performance and features a 48-pin LQFP package. Key electrical parameters include a maximum on-resistance of 38 Ω and an on-resistance matching specification of 1.52 Ω. It operates within a temperature range up to 70 °C and supports single-pole single-throw (SPST) functionality across its channels.

Feature Summary

• Integrates built-in bleeder resistors to accelerate voltage decay in capacitive loads
• Utilizes BCDMOS technology for high-voltage isolation and reliability
• Provides eight independent SPST analog switching channels

Applications

• High-voltage test and measurement equipment
• Data acquisition systems requiring fast settling times
• Automotive testing applications with capacitive loads

Procurement Notes

Verify the specific suffix designation against official IXYS documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with system voltage requirements and thermal management needs. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference part numbers with Littelfuse resources as IXYS Integrated Circuits Division operations have been integrated into their portfolio.

Selection Notes

Select this component when high-voltage isolation and rapid discharge capabilities are required for capacitive loads. The integrated bleeder resistors distinguish it from standard analog switches by reducing settling time significantly. Evaluate the 38 Ω on-resistance limit against signal integrity requirements. Consider the 48-pin LQFP footprint for PCB layout constraints and thermal dissipation characteristics in dense assemblies.

Part Context

The CPC7232 series belongs to IXYS's high-voltage analog switch family, formerly associated with Clare Inc. These devices are designed for applications demanding reliable switching of high voltages with minimal leakage. The integration of bleeder resistors addresses common issues with slow voltage decay in precision measurement circuits, offering a specialized solution compared to generic multiplexers.
