IQS232-00000000-SOR

Overview

The IQS232-00000000-SOR is a configurable two-channel capacitive touch and proximity sensor from Azoteq. It operates on a supply voltage of 1.8V to 3.6V with current consumption below 4 µA in low power modes. The device features automatic tuning implementation (ATI) for optimal sensitivity and drift compensation. It includes an internal voltage regulator, reference capacitor, and One-Time Programmable (OTP) memory for configuration. Outputs support direct logic levels or serial streaming via I2C-compatible interfaces. The component is housed in a compact SO-8 package.

Feature Summary

• Fully integrated two-channel capacitive sensing with differentiated touch and distributed proximity electrodes
• Automatic tuning implementation (ATI) ensures optimal sensitivity across varying environments
• Configurable output modes supporting both direct logic level signals and serial data streaming
• Advanced noise immunity with automatic drift compensation and RF noise detection capabilities

Applications

• White goods and home appliances
• Remote controls and office equipment
• Proximity detection for backlighting activation
• Wake-up triggers from standby modes
• Replacement for electromechanical switches

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure that any custom OTP configurations are programmed prior to final assembly if standalone operation is required without external programming tools. Cross-reference the package type and temperature rating with the system requirements before procurement.

Selection Notes

Select this component when a minimalist implementation with minimal external components is required. Consider the IQS232 for applications needing high sensitivity with automatic environmental adaptation. Evaluate the available low power modes against the required response time specifications. Ensure the design accommodates the SO-8 package dimensions and thermal requirements within the specified operating temperature range.

Part Context

The IQS232 belongs to the ProxSense series of capacitive sensors designed by Azoteq. It is part of the IQ Switch family, focusing on low-power, high-sensitivity touch and proximity detection. This model specifically offers two input channels and supports both touch and proximity functionalities within a single integrated circuit solution.

Replacement Considerations

The IQS232 is pin-compatible with the IQS132; however, designers must verify differences in electrical characteristics before substitution. No other direct replacement part numbers are documented in the provided datasheet.
