CAP1206-1-SL

Overview

The CAP1206-1-SL is a six-channel capacitive touch sensor controller manufactured by Microchip Technology. It features six individual capacitive touch sensor inputs with programmable sensitivity and automatic recalibration for parasitic capacitance compensation. The device supports SMBus and I2C communication interfaces, operates on a 3V to 5.5V supply, and draws up to 750µA during active sensing. It includes multiple pattern touch recognition, power button support, and an interrupt output. The component is housed in a 14-pin SOIC package and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Six independent capacitive touch sensor inputs with programmable sensitivity and automatic recalibration capabilities
• Multiple pattern touch recognition allowing simultaneous detection of specific button sets
• Low power operation with Deep Sleep state drawing 5µA typical current and Standby state consuming 50µA
• SMBus and I2C compliant communication interface with 8kV ESD rating on all pins

Applications

• Desktop and Notebook PCs
• LCD Monitors
• Consumer Electronics
• Appliances

Procurement Notes

Verify the manufacturer part number against official Microchip documentation to ensure authenticity. Confirm that the 14-SOIC package matches the design requirements. Check RoHS compliance status as specified in the datasheet. Ensure the operating voltage range of 3V to 5.5V aligns with the system power supply. Validate the I2C/SMBus interface compatibility with the host controller.

Selection Notes

Select this component when a multi-button capacitive touch interface is required without proximity detection. Consider the 14-SOIC package size for PCB layout constraints. Evaluate the power consumption profiles if battery operation is critical, noting the Deep Sleep mode. Ensure the host system supports SMBus or I2C protocols for configuration and data retrieval. Verify thermal performance within the specified -40°C to 125°C operating range.

Part Context

The CAP1206-1-SL belongs to the CAP1206 family of capacitive touch sensor controllers from Microchip Technology. This family provides solutions for replacing mechanical buttons with touch-sensitive interfaces. The -SL suffix indicates the specific 14-SOIC package variant. Other variants in the series may offer different channel counts or packaging options.
