TSL2672 Overview
The TSL2672 family of devices provides proximity detection when coupled with an external IR LED. The devices incorporate a constant-current LED sink driver to pulse the external IR LED and achieve very low average power consumption using the low-power wait state with programmable wait time between proximity measurements. In addition, the devices are register-set and pin-patible with the TSL2671 series and include a...
