IQS377
The IQS377 ProxFusion® IC is a sensor fusion device for multi-level analogue sensing. An additional channel can be used in tandem to increase the reliability and accuracy of the multi-level trigger solution. The sensor is fully I²C compatible, and on-chip calculations enable the IC to respond effectively even in the lowest power modes.
