In the consumer markets, the ICs are used in a variety of consumer electronics including mobile phones, consumer video players, digital cameras, keyboard devices, and safety controls. In the manufacturing industry, they can be used to detect complete fluid control, opto-electronics in consumer goods, and production of semiconductor devices. Medical devices such as bionic infra-red controls and bio-sensors are also benefitting from its use in allowing very small to large distance measurements.

The RE46C166SW16F is designed to be combined with the RE46C166SW16F-compatible switches, relays, and digital output modules. It uses a 4-wire interface in combination with capacitive sensing technologies to allow for both a fast response time and a very low power consumption. It features a low standby power consumption of only 8mW and an ultra low current consumption of only 6µA, making it one of the most energy efficient ICs in the market. The IC also features a wide range of voltage options ranging from 2.5V to 5.5V.

The working principle of the RE46C166SW16F is based on a key switch input, which is connected to a single capacitor. When the key switch is turned dow over 5 times, the capacitor is charged and discharges at a certain rate. During that time, the capacitor transfers the electric charge to an internal metal oxide semiconductor field-effect transistor (MOSFET), which is used to detect the capacitance of the key switch. The current flowing through the MOSFET is the Voltage Drop (Vds) of the field effect transistor. As the Vds changes depending on the key switch’s input, this current eventually reaches a threshold value where an ON or OFF signal is generated, thereby enabling or disabling the integrated circuit.

The RE46C166SW16F provides precision detection, fast switching, and low power consumption, which makes it a great choice for applications in any environment. Its 4-wire interface in combination with the MOSFET integrated circuit make it a versatile solution for a wide range of applications – from consumer electronics to medical equipment and manufacturing.
