ISO7021FDR  

Digital Isolators

The ISO7021FDR is a high-performance, low-power, single-channel, capacitive touch sensor controller from Texas Instruments (TI). It is designed to provide a robust and accurate touch sensing solution for various applications, including industrial, automotive, and consumer electronics.

Description:

The ISO7021FDR is a member of TI's CapTouch® family of devices. It is a fully integrated, low-noise capacitive touch sensor controller that operates over a wide supply voltage range (2.7V to 5.5V). The device features an integrated charge pump, which eliminates the need for an external high-voltage supply, simplifying the overall system design.

Features:

1. Single-channel capacitive touch sensor controller
2. Wide supply voltage range: 2.7V to 5.5V
3. Integrated charge pump for high-voltage generation
4. Low power consumption: 3.5µA in active mode and 0.5µA in standby mode
5. Programmable sensitivity and baseline drift compensation
6. On-chip oscillator and clock management
7. Configurable touch detection threshold
8. Support for self-capacitance and mutual-capacitance sensing
9. I2C and SPI communication interfaces
10. Small package size: 6-pin WSON

Applications:

The ISO7021FDR is suitable for a wide range of touch sensing applications, including but not limited to:

1. Industrial control panels
2. Home appliances (e.g., washing machines, refrigerators, ovens)
3. Automotive applications (e.g., infotainment systems, climate control panels)
4. Consumer electronics (e.g., smartphones, tablets, gaming consoles)
5. Medical equipment
6. White goods (e.g., dishwashers, microwaves)
7. Building automation systems (e.g., lighting control, HVAC control panels)
8. Fitness equipment (e.g., treadmills, exercise bikes)

The ISO7021FDR's low power consumption, high accuracy, and ease of integration make it an ideal choice for designers looking to incorporate capacitive touch sensing into their projects.
