Hello,
Congratulation for your great job about the CJ125 !
I have also a project for motorsport with this chip CJ125. I understand that I need to driver the "Heater " with an external mcu, a PWM and a mosfet. The value of this PWM depends of the UA in the CJ125. UA depends before of Ri and the temperature, but what is the link, the formula between the Temperature in °C en the LSU4.9 and Ri or UA. I dont find the formula, so how can I know if the MCU must drive the MOSFET to heat or not?
Many thanks for your help,
Arnaud

Re: rusEfi own wide band controller board add-on using CJ125
Hi everybody,
i currently did a board by my own with the CJ125 and unfortunately there is a shortcircuti between pin 6 & 7 and 18 & 19 in the SOIC 24 package. Is this normal? Or is this a fake chip which i bought @ebay?
Thank you in advance

Since CJ125 is no longer available from reputable sources and since we have https://github.com/mck1117/wideband/ option CJ125 hardware is moved to hw_legacy and this thread is now marked "DEAD DESIGN"
