Hi ,
I want to design a linear thermo electric cooler driver with analog PID control. The maximum I,V ratings of the module is 5.8A,15.7V.The input supply volatage is not a problem.
I was looking on to the part numbers OPA 549 .Can this IC could both sink and source 8A continuous while running from a single positive supply?I was thinking about using this two of these parts directly to drive a TEC as mentioned in opa569 datasheet
I was also looking on to the "OPTOELECTRONICS CIRCUIT COLLECTION" by By Neil Albaugh of SBEA001 - SEPTEMBER 2001 from TI which has Linear TEC drvies
exapmles for upto 2A using A bridgetied load (BTL) amplifier topology.
Is it possible to extend this circuit to higher currents & voltage ranges by changing the transistors at output?
Can somebody tell me which would be the best topology among above listed?
Regards
Stephen Thomas
