IQS620A-0-DNR

Overview

The IQS620A-0-DNR is a multifunctional sensor interface IC from Azoteq's ProxFusion series, integrating dual-channel capacitive proximity/touch sensing, Hall-effect detection, and inductive sensing within a single platform. It operates on a supply voltage range of 1.8V to 3.3V and features an I2C-compatible digital interface with optional RDY interrupt signals. The device supports various user interfaces including SAR, hysteresis, and wake-up modes, designed for ultra-low power consumption across different response rates. It is housed in a DFN(3x3)-10 package suitable for surface mount applications.

Feature Summary

• Combines capacitive, Hall-effect, and inductive sensing technologies in one integrated circuit
• Features Automatic Tuning Implementation (ATI) for stable performance across varying environmental conditions
• Supports multiple configurable user interfaces including SAR, proximity wake-up, and hysteresis modes
• Provides flexible GPIO outputs for direct trigger events such as SAR activation or ready signals

Applications

• Mobile electronics including phones and tablets requiring SAR safety compliance
• Wearable devices needing low-power multi-modal sensing
• White goods and home appliances utilizing proximity or touch controls
• Human Interface Devices (HID) with gesture or button inputs

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through official datasheets prior to integration. Check for any product change notifications that may affect pinout or electrical characteristics. Ensure supply chain stability by reviewing lead times and availability directly with authorized distributors.

Selection Notes

Select this component when a design requires simultaneous support for capacitive, magnetic, and inductive sensing modalities without increasing board space. Consider the DFN(3x3)-10 package constraints regarding thermal dissipation and footprint clearance. Evaluate power budget requirements against the specified current consumption values for the desired sampling rate and active channels.

Part Context

This part belongs to the IQS620A family within Azoteq's ProxFusion line, which focuses on combining multiple sensing technologies. The -DNR suffix indicates the DFN(3x3)-10 package variant. It serves as a successor or alternative to older discrete sensor solutions, consolidating functionality into a single microcontroller-integrated sensor hub for compact electronic designs.

Replacement Considerations

The IQS620A-0-CSR is the WLCSP-9 package equivalent within the same functional family. For legacy replacements, check the IQS620A-0-DNR discontinuation notices if applicable, though current data suggests it remains active. No direct cross-brand substitutes are officially documented; verify pin compatibility and software register maps when considering alternatives.
