Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
I am developing a solution using a STWBC2-HP tx running from a 24VDC supply to drive a STWLC99 rx and need to use the STSC protocol to achieve 50~100W. This is for bespoke power transfer rather than a conventional charger. I am basing the design on t...
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...
Hi, I'm designing a driver using 3x STSPIN9P12 to drive a Permanent Magnet Synchronous motor (PMSM). I have a ADC connected to the SNSO outputs to measure current and I am controlling the current in the MCU's control loop. I am not using the COUT a...
Hi,We are designing a compact, battery-powered system that requires a regulated high-voltage DC output with the following specifications:• Input: 5V• Output: Adjustable 400V to 1000V• Load current: 1µA to 200µA• Very low ripple and noise• High effici...
Hello everyone,We are currently working on structural validation and material testing workflows.Has anyone here implemented automated reliability testing setups?We documented some testing methods and validation ideas here:Would love to hear your feed...
Hi . I'm using STGAP2D SO-14 IC in custom project with custom board , and in datasheet i see pin8 specified as N.C. (not connected). Pin8 must be left floating for ic to function properly , or can it be connected to nearby pin7 (GND) ? Is this pin i...
The L6206Q datasheet Figure 14 "Typical Application" does not show the use of any additional SENSE_A or SENSE_B resistors connected to pins 45/46 & 15/16 respectively. Section 4.3 talks about "the external current sense resistor normally used [being...
Hello Team,I am using the STUSB4500 USB Power Delivery controller in my design.I have designed my board by strictly following the reference schematic provided in the STUSB4500 datasheet. However, the board is not working as expected.I have already tr...
For the analysis and working of the gate driver L6491, we need the simulation model of the gate driver L6491 of LTspice or Pspice. Please provide the simulation model as soon as possible. It would be very helpful to us.Thank you!
Hello,We completed a test of bi-driectional communication of the Proprietary Packet feature (PP) for a mass market client using the STWLC38 (RX) and STWBC86 (TX).We're able to consistently receive the data of 5 bytes reliability from the RX to the TX...
