DO5022H-153MLD - Brand New Coilcraft IC Chips
-
Description
The DO5022H-153MLD is a monolithic controller designed for driving a thermoelectric cooler (TEC). It is commonly used to stabilize the temperature of laser diodes or passive components in telecommunications equipment. This device utilizes a negative temperature coefficient (NTC) thermistor to sense the temperature of the attached object. The target temperature can be set using an analog input voltage from a DAC or an external resistor divider. The controller features a PID compensation amplifier with high stability and low noise, and the compensation network can be adjusted for optimal temperature settling time. It also provides voltage outputs for monitoring both the temperature and the voltage across the TEC, with a 2.5V voltage reference included.
