I have a DRV8838 in usage that is supposed to trigger a solenoid. The logic circuit is powered with 3.3V and controlled by an ESP32 which all works fine (i can see voltage raise and fall for PHASE and ENABLE pin as the ESP32 triggers HIGH and LOW)
The motor circuit is powered with 9V (originating from an S10V3F9) and i can measure that voltage alright at the VM pin. But Vout1 and Vout2 only give me stable 3.05V (i can see that also they drop to 0V if the ESP32 triggers the ENABLE PIN)
If i replace the DRV8838 with a second one i have it gives me 0V for Vout1 and Vout2.
What could the source for that problem (not getting expected 9V)? (i did not really pay attention in school when it came to theory of electricity so i am wandering in the dark here)
