Hi all,
Continuing on trying to build a fully automatic high frequency PWM fan circuit with speed controlled by temperature in fully automatic manner, I found this amazing product - MAX31740 but I'm not a huge fan of TDFN packages so I'm trying to find something similar but with pins (SSOP etc).
It seems that this IC does not require any MCU to run, which is what I'm looking for but I can't find anything equivalent.
The use case:
Mini-PCB to control 12v 1A 4-pin PWM FAN (one or more). Ability to control speeds between temperatures of 50 °C and 100 °C starting the fan at 25% RPM and up to 100% when reaching max temp.
Circuit will "turn on" by thermal switch (normally open) placed on the monitored component, that activates at 50 °C. Also going to use 1 SMD potentiometer for better flexibility setting up the board and using different types of fans down the line.
I'm currently learning how to program with Arduino as well.
