IQS211B00060000TSR

Overview

The IQS211B00060000TSR is a single-channel self-capacitance controller 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 including activation and movement signals, supporting up to 60 pF sensor load for proximity and 120 pF for touch applications. 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
• Automatic Tuning Implementation (ATI) for environmental compensation
• Configurable primary and secondary digital outputs
• Supports both I²C communication and standalone direct output modes

Applications

• Wearable devices requiring motion awareness
• Movement detection systems such as fitness trackers and anti-theft alarms
• White goods and home appliances with proximity controls
• Human Interface Devices (HID)
• Proximity activated backlighting systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm package type and pre-programmed OTP settings. Confirm that the requested quantity matches the standard tape and reel specifications provided by the authorized distributor. Ensure compatibility with the required operating temperature range of -40°C to +85°C for the IQS211B variant before finalizing procurement orders.

Selection Notes

Select the IQS211B over the IQS211A when operation in extended low-temperature environments below -20°C is required. Verify that the application requires a single channel with combined proximity and movement capabilities. Ensure the system design accommodates the TSOT23-6 or DFN-6 package options available for this model. Confirm interface requirements for either I²C polling or standalone GPIO configurations.

Part Context

This component belongs to the Azoteq ProxSense series of capacitive sensors. It serves as an upgrade to previous generations like the IQS127D/128 and IQS227AS/228AS, offering improved temperature response characteristics. The IQS211B variant specifically extends the operational temperature range compared to the IQS211A, making it suitable for harsher industrial or outdoor environments.

Replacement Considerations

Pin-compatible replacements include IQS127D, IQS128, IQS227AS, IQS228AS, and IQS231A, though output types may differ. Verify firmware configuration compatibility when migrating from these legacy parts. The IQS211A is functionally identical in firmware but lacks the extended low-temperature rating.
