Resolved! VLxx voltage limit on STPMIC1DPQR
V SWITCH_MIN (VLXx)is measured below the the absolute maximum rating on datasheet (-0.5V).However this limit is momentary ony (7.2 ns) as shown on the measurement.Usually datasheet specifies the minimum DC limit and minimum limit during transient val...
Wireless Charging - Transmitter
Hello,I am looking at the STEVAL-ISB027V1 dev board. I see that it is obsolete. That is fine, I am more interested in understanding if this design could be implemented on 6x independent channels of Tx coils. I want to be able to independently control...
Resolved! Understanding Max Current Specifications for VNH motor driver family
Hi, I'm trying to spec a fully integrated H-bridge for driving a small motor taking up to 6A nominal, with spikes up to 12A (looking at the VNHD7012AY, VNHD7070AY, and the VNH7100BAS). There are a lot of numbers for current limitation on the ST datas...
STEVAL-A6986IV3 grounding capacitors
Hello, I am strongly considering using the STEVAL-A6986IV3 based design for a 4 channel isolated gate driver power supply. One thing that looked strange in the the schematic was the four ground capacitors Cgnd1,2,3,4 which are 4.7nF 2000V rated. The...
Resolved! Questions about to Auxiliary power supply with VIPER06
HiI have a question about the conection of VIPER06 module as auxiliary power supply. I Have a power stage PFC with L6562 and two capacitor in series as outuput capacitor. Then, i need a 15V aux power supply. Can i connect the VIPER06 Flyback stage,...
Resolved! L6982C33DR & L6982C50DR always provide 2.5V output
Dear Community,I’m currently testing the L6982C33DR and L6982C50DR to supply 3.3V and 5V to my board.I followed the reference design provided in the user manual and completed the PCB layout accordingly.However, when I power the board with 12V (Power+...
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 “...
