Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
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...
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.
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 “...
Hello everyone,I got the above mentioned Eval boards with the following adaptions to suit my application:- Tx coil connected to STEVAL-WBC86TX: WE 760308101104 - Rx coil connected to STEVAL-WLC38RX: Custom PCB antenna with ~1.5 µH self-inductance, ~...
Is VNF1048FTR of ASIL B compliance? If not can you suggest any E fuse with ASIL B compliance with 48V system, with SPI, current sense
Hello, Good Morning Can i design SMPS using HVLED007 which should work on universal input and should provide 24v 2amp at its output it is PFC too. The most challenging part is to calculate and wind flyback transformer. I've some transformer bobbins a...
Hello We are currently working on programming the STPMIC25APQR Power Management IC and are facing some issues related to the LDOs.As per the datasheet, there are no NVM control registers for LDO1 and LDO4, with their default output voltages specified...
Hi team, I have a question about L9396 VBST and VB voltage. The normal operation voltage rage of VBST and VB pin is (-0.1V,19V), and the absolute maxmum ratings of VBST and VB pin is (-0.3V,40V). So, in case that the voltage is (19V, 40V), what will...
Hi I'm using the part STNS01 with a Li-Polymer batter of 6mAh (nominal capacity).. I've used a 13KΩ resistor for to set current charge limit which provides 15mA as the output for the CCCV charging. Would there be any issue with using a 6mA batte...
