IQS211B00060000DNR

Overview

The IQS211B00060000DNR is a single-channel self-capacitance controller from the Azoteq ProxSense series, designed for proximity and touch detection with integrated movement sensing. It operates on a supply voltage of 1.764 V to 3.6 V and supports I2C or standalone interfaces. The device features Automatic Tuning Implementation (ATI) and Internal Capacitor Implementation (ICI). It offers configurable outputs for activation and movement events, supporting pulse frequency modulation (PFM), pulse width modulation (PWM), or latched states. Power consumption ranges from sub-2 µA in low-power mode to 80 µA at 50 Hz response.

Feature Summary

• Integrated on-chip movement detection algorithm for long-term activation applications
• Automatic Tuning Implementation (ATI) for environmental compensation without MCU interaction
• Configurable primary and secondary digital outputs for activation and movement status
• Supports both I2C communication and standalone direct output modes

Applications

• Wearable devices requiring proximity wake-up
• Movement detection systems such as fitness trackers and anti-theft alarms
• White goods and home appliances with touch controls
• Human interface devices utilizing swipe or touch functions
• Proximity activated backlighting systems

Procurement Notes

Verify the specific ordering suffix DNR against the manufacturer's current datasheet revision to confirm package type and pre-programmed OTP settings. Ensure compatibility with the required operating temperature range of -40°C to +85°C for the IQS211B variant. Confirm that the selected configuration matches the intended application requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel solution with integrated movement detection is required. The IQS211B variant provides an extended low-temperature range compared to the IQS211A. Consider the available packages, including TSOT23-6 and DFN-6, based on board space constraints. Verify that the sensor load capacitance requirements fall within the supported limits for either proximity or touch applications.

Part Context

This part belongs to the Azoteq IQ Switch ProxSense series, which focuses on ultra-low power capacitive sensing solutions. The IQS211B variant specifically enhances performance in lower temperature environments while maintaining identical firmware capabilities to the IQS211A. It serves as a minimalist implementation option for designers seeking to reduce external component counts through internal calibration features.

Replacement Considerations

The IQS211B is pin-compatible with the IQS127D, IQS128, IQS227AS, and IQS228AS families, though output types may differ. Designers should verify electrical characteristics and pin assignments carefully when substituting these parts. The IQS211A shares the same firmware but lacks the extended low-temperature rating of the IQS211B.
