IS32SE5117A
DESCRIPTION
IS32SE5117A is an ultra-low-power, 16-channel capacitive touch controller. The controller allows sleep mode (under 10u A) and uses auto-detection for wakeup. It also provides a shield output to increase moisture immunity. The built-in hardware monitor and calibration for the environment is to prevent false triggers.
A host MCU is required to municate with IS32SE5117A. An on-chip I²C slave controller with 400k Hz capability serves as the munication port for the host MCU. An interrupt, INT, can be configured and it is generated when a touch trigger event occurs. Trigger conditions can be configured by setting the interrupt register. IS32SE5117A can support proximity sensing.
IS32SE5117A is available in the wettable flank QFN-24 package. It operates from 2.7V to 5.5V over the temperature range from -40°C to +125°C.
