The CAP1203-1-AC3-TR is a capacitive touch sensor controller from Microchip Technology designed to detect touch inputs. It supports up to 3 capacitive touch buttons and communicates via an I²C or SMBus interface.
Electrical specifications include a supply voltage range of 3V to 5.5V and a typical supply current of 500µA. The device operates over an industrial temperature range of -40°C to 125°C, making it suitable for harsh environments.
The controller is housed in a compact 8-WFDFN exposed pad package, with a supplier device package of 8-TDFN (3x3 mm). It is surface mountable, allowing for automated assembly. The device does not include proximity detection; it is designed for direct button sensing.
Typical applications include user interface controls, consumer electronics, and industrial panels where capacitive touch buttons are required. The I²C interface enables easy integration with microcontrollers and other digital systems.
