l6235 brake issue
i have a design using the L6235 motor controller. when the motor is running at 4800 I applied the brake and disabled the enable pin of the IC, all worked fine, But i was getting the motor overrun because of the inertia of the gears.I tried to applied...
Resolved! STEVAL-IPM10B Evaluation Board Purpose of "PWM_Vref" Pin
Hello again, dear STMicroelectronics team,While reviewing the schematic sheets of the STEVAL-IPM10B Evaluation Board, I came across a connector pin labeled 'PWM_Vref' (highlighted with a green circle in the image below). However, I couldn't find this...
Resolved! STGIB10CH60TS-L Isolation Issue
Hello, would it cause any issues if 'PWR_GND' (highlighted in green) and 'SGN_GND' (highlighted in pink) are not referenced to the same ground?Thank you in advance. Best regards.
T1610T-8i won't turn off above 60c, should work to 100c
I apply three phases at 115vac, 400hz.I apply a 10A load. I turn on the Opto-Triac (VOT8121AB), and current runs thru the Triac under test(TUT) (T1610T-8i) and ac voltage appears at the output (ex; see CSSI_R_PhaA_Out, loc=A5, of Attached schematic “...
