Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
I purchased the EVALSTGAP2HS board for evaluating STGAP2HS gate drives. I'm disappointed in the available documentation for this board, but finally I deduced that the only correct way toconnect devices is as shown in the figure I'm a bit puzzled by ...
Hello, We are currently integrating the SPSB081 PMIC for voltage and wake-up management in a Body Control Module (BCM). The PMIC is interfaced with an NXP S32K312 MCU via SPI.System Setup:MCU: NXP S32K312 (100-pin package)PMIC: SPSB081Communication: ...
We are currently using the PM8805 in our PD (Powered Device) design.We have recently encountered field failures and suspect that the root cause lies in the customer's testing process.Our customer was using a Passive DC Injector (55V DC Supply) instea...
Hi,We wish to do a Boost PFC with L4986A and a 30uH inductor.Power is 2200W and Mains is 85-265VAC.When the mains is at 240VAC, the inductor current would be discontinuous for some 80% of the mains half cycle.Is this OK?Will the L4986A be able to c...
I am designing a 3-phase AC to 24 V DC power supply and plan to use the VIPER26K high-voltage converter (as used in the STEVAL-VP26K02F evaluation board) as the main switch-mode controller in a flyback/isolated design. The target specifications are:I...
Hello,I am a graduate student working on power electronics research.I am using STDRIVEG600 in my experiments and simulations.I would like to ask if any simulation model is available for STDRIVEG600.If available, please advise how I can obtain it.Than...
Both the BoM and Schematic (in the Data Brief) do not show the part numbers or values for L2 and L4 on the STEVAL-STPM801 ORing circuit. Which inductors are used on the reference design? Thank you.
We are students that are trying to make a multi frequency power system interconnection model with a dc link similar to real life back to back hvdc, and we need a converter that supports bidirectional power transfer, is it possible for STEVAL-IPM15B t...
Hello everyone, I’m having an issue reading the current sense (CS) output from a VND7040 using an STM32G473 ADC. When driving a DC motor with PWM: • At ~50% duty cycle, I measure around 500 mV on the CS signal (after RC filter) using an oscilloscope•...
Hi ST,It has been more than a year since STEF48H28 was announced (document DB5404 dated Nov 2024).When is it going to be available for preview?I would prefer to use ST’s solution over a comparable device already available as evaluation module from a ...
