ADN8831 Thermoelectric Cooler (TEC) Controller
Analog Devices Inc. ADN8831 Thermoelectric Cooler (TEC) Controller is a monolithic TEC controller with two integrated, zero drift, rail-to-rail comparators, and a unique PWM driver. This highly integrated device controls the TEC in a laser module used in optical communications systems. The PWM driver works with an analog driver to control external selected MOSFETs in an H-bridge. By sensing the thermal detector feedback from the TEC, ADN8831 can drive a TEC to settle the programmable temperature of a laser diode or a passive component attached to the TEC module.
