B6TS-08NF

Overview

The B6TS-08NF is an 8-channel capacitive touch sensing integrated circuit manufactured by Omron Electronics Inc-EMC Div. It operates within a supply voltage range of 4.5V to 5.5V and supports an ambient operating temperature from -20°C to 85°C. The device features SPI serial communication with a clock cycle time of 8650ns and includes EEPROM for configuration storage, rated for 10,000 write cycles and 20 years data retention at 55°C. Normal measurement mode current consumption is 4mA, reducing to 0.4mA during sleep.

Feature Summary

• Adaptive environmental tolerance with self-teaching, auto threshold, and intelligent filtering capabilities
• Continuous compensation for long-term drift and resistance to electromagnetic interference (EMC)
• Flexible panel design freedom allowing use of various non-conducting materials such as plastic, glass, or wood
• Configurable output modes including momentary switching, latching switching, and serial data via SPI interface

Applications

• Dishwasher control panels
• Washing machine interfaces
• Oven controls
• Fitness equipment displays
• HVAC systems

Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the power supply strictly adheres to the 4.5V to 5.5V operating range to ensure stable performance. Check for RoHS compliance status if required by local regulations. Ensure proper ESD handling procedures are followed during assembly and testing phases.

Selection Notes

Select this component when an 8-channel capacitive solution is required for embedded MMI applications. Consider the B6TS-04LT for fewer channels or the B6TS-16NF for higher density needs. Evaluate the need for SPI communication versus simple GPIO outputs based on system complexity. Verify that the target enclosure material allows for sufficient capacitive coupling without excessive thickness.

Part Context

The B6TS-08NF belongs to the B6TS family of capacitive touch sensing ICs, which expands Omron's switch product range. This family utilizes a capacitive measurement principle to detect touch events through non-conductive surfaces. The series includes variants with 4, 8, and 16 channels to accommodate different interface densities.

Replacement Considerations

No direct public substitute part numbers are documented in the provided source material. Designers should evaluate other 8-channel capacitive touch controllers from Omron or third-party manufacturers if this specific part becomes unavailable.
