Hello,
I am using an 74HC595 shift register and two BTS716G MOSFET switches to control a number of electronic valves with an Arduino.
On the output of the shift registers (and input to the MOSFETS) I am getting 5V pulses that I am expecting. However on each of the output channels of the MOSFET, the voltage is not GND on a LOW input (it is somewhere around 7.9V - 8V). On HIGH, the MOSFET is properly sourcing 12V.
I am not sure why the voltage is not GND when pulled LOW on the input.
Attached is photo of 1 of the output channels and the schematic of the driver circuitry (blue labels represent the channel output).
