hi
we have to drive injector with IC BTS3035EJ. as following
we have given pwm siganl at pin no 1 which is "INJECT_OUT_CTRL_MCU " from mcrocontroller. we didnt receving at pin no 9 output which is used to drive injcetor.' onepin of injcetor is connected to 12 volt another one is INJECT_OUT of this IC.
what is the role of pin no. 3 which is "status" how i embedded this in my firmware so that my injector starts operating
thansk
Hello,
Status pins is a feedback pin which sets high to know when a fault happens. The device pulls the STATUS pin down to GND pin by an internal pull down intend to signal a low level to the microcontroller.
I can see you have connected the resistors properly as mentioned in the application circuitry example.
1. Can you share the oscilloscope result at STATUS pin ?
2. Try removing the capacitor C76 and check the results if the problem still persists.
Best Regards,
