VNL5030J-E Propagation Delay failing
Hello STmicro Team, I have done a propagation delay analysis using VNL5030J-E. The Delay-on time, rise time and delay-off time does not matches with the datasheet Values. Please check and let me know your feedback in this. I am attaching here the sna...

Resolved! power MOSFET spice models
I am trying to get the spice model for STW3N170 MOSFET, it does not seem to be with the other info for the devive.Any help appreciated. Paul
STPM32 RESET
Hi,We are using STPM32 with LPC controller, when observing the startup reset pulse we are getting as in the picture attached. Both SYN and SCS pins are initialized high but when powered on SYN is coming low for some time then it is taking 35ms delay ...
ST8R00WPUR boost converter output temporarily drops under load
Hello, I am having a problem with a design using the ST8R00WPUR.The input is 5v, the output is 10.5v, the load is 22 ohms (477mA).The problem is that the output drops below 3v for 200ms when the load is applied, before returning to 10.5v. The problem...
Resolved! L9026 Device ID Value
Recently started working on the L9026 Device, as an initial setup, trying to read the Device ID. With The L9026 Evaluation board Device ID is read as 0x55, With L9026 Placed on the Our Target Board, Device ID is read as 0x56, Was surprised with t...
Issue with L6599AD : Unable to generate PWM pulses from HVG (PIN15) and LVG(PIN11).
Dear ST Community Member,Currently working on development of 1.2kW EV Charger. The L6599AD (high-voltage resonant controller) IC is used for half-bridge LLC topology. We have tested the IC separately by giving different voltages at various pins of th...
Resolved! L99MH98
I would like to know the working principle of the charger bump for MH98, as well as the working principles of CPOUT, CP1, and CP2. Why can the voltage of the bootstrap capacitor reach 11.3V when VDH = 6V? In other words, why can the voltage of CP rea...
Resolved! LDL212PUR bypass capacitor requirements
Hi all. The data sheet for the LDL212PUR low dropout linear regulator does nor specify the quality of the input and output bypass capacitors with regard to ESR or loss tangent requirements. Most LDO regulators require at least one low ESR bypass cap...
Please reply my question regarding L9369 GIO
I am writing because I have a question about the L9369 chip. The second case of above table ( SPI_GIOx_HSCtrl == 0 and SPI_Off_Giox == 1) , Output is set to HIGH. I'm curious why GIOx Output is HIGH when SPI_GIOx_HSCtrl is 0. Thank you.
