Product Summary
The SI7904DN-T1-E3 is a monolithic controller that drives a thermoelectric cooler (TEC) to stabilize the temperature of a laser diode or a passive component used in telecommunications equipment. This device relies on a negative temperature coefficient (NTC) thermistor to sense the temperature of the object attached to the TEC. The target temperature is set with an analog input voltage either from a DAC or an external resistor divider. The applications of the SI7904DN-T1-E3 include Thermoelectric Cooler (TEC) Temperature Control, Resistive Heating Element Control, Temperature Stabilization Substrate (TSS) Control.
