The LC71F7001VB-0-TLM-H is a part of the F7000 Series of capacitive touch-sensing ICs from NEC that brings an enhanced user experience to capacitive touch-sensing.

The F7000 Series capacitive touch ICs feature NEC’s proprietary “Capacitive Touch Converter” (CTC) technology, which is well-suited for use in mesh-type interconnects and support for fast, accurate touch input for a wide range of applications.

The LC71F7001VB-0-TLM-H is ideal for use in a variety of applications, including medical and automotive control panels, home theater and home appliance control panels, gaming systems, robotics, and industrial and consumer products. The IC is designed to operate in environments affected by contact noise, allowing touch paneling processes to be performed even under environments with wet hands. This eliminates the need for a conventional contact type touch panel which requires manual contact, thus eliminating the possibility of contact noise.

The LC71F7001VB-0-TLM-H has a built-in noise filter that enables it to maintain a low detection threshold and a high sensing speed. The touch input is processed quickly and the detection result is promptly sent to the host microcontroller. The IC also offers a wide dynamic range, which allows it to gauge subtle or quick touch inputs with the same degree of accuracy.

The working principle of the LC71F7001VB-0-TLM-H is based on capacitive touch sensors, which measure the capacitance between a human finger or stylus and the electrodes installed in the touch panel. These capacitance changes, which are affected by various factors such as finger movement and hand motion, are detected and processed by the IC’s built-in capacitance-to-digital converter. The touch input is then sent to the host microcontroller for further processing.

The LC71F7001VB-0-TLM-H capacitive touch IC also features integrated temperature compensation and temperature detection, thus providing enhanced temperature protection against thermal damage. It also offers integration of multiple sensors on one IC, allowing the user to easily monitor multiple inputs at once.

In addition, the LC71F7001VB-0-TLM-H provides a wide range of functions such as analog level output, built-in test pins, and management of multiple pins to support a variety of user-defined applications. The IC also offers a multi-channel configuration, allowing for a single-wire control system to be configured for applications such as robotic and automation systems.

Overall, the LC71F7001VB-0-TLM-H capacitive touch IC is an ideal choice for applications that require fast, accurate touch input with enhanced noise reduction capabilities. The IC’s wide dynamic range and wide-range temperature compensation make it an excellent choice for a broad range of applications.
