SI7446DP-T1-E3 - Brand New VISHAY IC Chips
-
Description
The SI7446DP-T1-E3 is a model of electronic component belonging to the IC Chips product category. It is a monolithic controller designed to stabilize the temperature of a laser diode or a passive component used in telecommunications equipment. The temperature is regulated using a negative temperature coefficient (NTC) thermistor to sense the temperature of the attached object. The desired temperature can be set using an analog input voltage from a DAC or an external resistor divider. The device utilizes a PID compensation amplifier with high stability and low noise to maintain temperature stability. The compensation network can be adjusted by the user for optimizing temperature settling time. Voltage outputs are provided for monitoring the temperature and the voltage across the thermoelectric cooler (TEC). The device also features a voltage reference of 2.5 V.
