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.
Do you have a solution for wBMS?
Hi~ I am curious about the solution which referred to the wBMS I heard that you have BMS solution SOC. But I haven't heard about the wBMS. If you have, please let me know it Many thanks BRs Daniel Lim
Resolved! LED1202QTR
Hello ST Team,We are observing that LEDs are minor glowing, during turn off condition due to leakage current. As per our application we are not not using any PWM configuration for LEDs. We are just making LEDs turn ON/OFF as per application requireme...
