IQS127D-00008-TSR

Overview

The IQS127D-00008-TSR is a single-channel capacitive proximity and touch controller from the Azoteq ProxSense series. It operates on a supply voltage of 2.95V to 5.5V within an industrial temperature range of -40°C to +85°C. The device features Automatic Tuning Implementation (ATI) and an internal reference capacitor, requiring minimal external components. It provides dedicated Touch (TOUT) and Proximity (POUT) outputs with configurable logic levels and modes. Power consumption ranges from 13µA in Low Power Mode 2 to 77µA in Boost Mode.

Feature Summary

• Automatic Tuning Implementation (ATI) for optimized sensor performance across varying environmental conditions
• Internal Capacitor Implementation (ICI) eliminating the need for external reference capacitors
• Configurable output modes including active, latch, and toggle states for both proximity and touch events
• One-time programmable (OTP) user options allowing selection of power modes and sensitivity thresholds

Applications

• LCD, Plasma & LED TVs
• GSM cellular telephones – On ear detection / touch keys
• LED flashlights or headlamps
• White goods and appliances
• Office equipment, toys, sanitary ware

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm factory configuration settings. Ensure the TSOT23-6 package matches the target PCB footprint. Confirm RoHS2 compliance requirements are met for the intended market regulations before finalizing procurement orders.

Selection Notes

Select this component when a single-channel solution with integrated ATI is required. Verify that the operating voltage range of 2.95V to 5.5V aligns with the system power supply. Consider the available power modes if battery life is a critical design constraint. Ensure the application does not require multiple independent sensing channels.

Part Context

The IQS127D belongs to the Azoteq IQ Switch ProxSense family of capacitive sensors. This series focuses on low-power, high-reliability touch and proximity detection using proprietary charge transfer technology. The IQS127D specifically targets applications needing a simple, single-sensor interface with robust noise immunity and automatic calibration capabilities.
