IQS211B00060000CSR

Overview

The IQS211B00060000CSR 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 1.8 V to 3.6 V and supports I2C communication alongside standalone direct output modes. The device features automatic tuning implementation (ATI) and configurable One-Time Programmable (OTP) settings. It is housed in an 8-ball Wafer Level Chip Scale Package (WLCSP-8) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated on-chip movement detection algorithm that forces activation upon detecting motion.
• Supports both standalone operation via configurable digital outputs and I2C interface for system integration.
• Includes Automatic Tuning Implementation (ATI) to automate environmental compensation without microcontroller interaction.
• Offers multiple low-power operating modes, including sub-2 µA standby with wake-up capabilities.

Applications

• Wearable devices requiring long-term activation
• Movement detection systems such as fitness trackers and anti-theft alarms
• White goods and home appliances
• Human Interface Devices (HID)
• Proximity activated backlighting

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and pre-programmed OTP configurations. Ensure the component matches the required operational temperature range and supply voltage specifications for the target application environment before finalizing procurement.

Selection Notes

Select this model when a single-channel solution with integrated movement detection is required. The IQS211B variant provides improved temperature response compared to the IQS211A. Consider the WLCSP-8 package for compact designs or alternative packages if pin compatibility with legacy sensors like the IQS127D is necessary.

Part Context

This component belongs to the IQ Switch ProxSense series by Azoteq. It serves as a specialized sensor interface for applications demanding ultra-low power consumption and reliable proximity or touch sensing. The IQS211B offers hardware improvements over the IQS211A while maintaining identical firmware functionality.

Replacement Considerations

The IQS211A is pin-compatible but lacks the improved temperature response of the IQS211B. Legacy replacements include the IQS127D, IQS128, IQS227AS, and IQS228AS, though output types may differ.
