L6482 current control parameters
Hi,I am concerning about the L6482 current control parameters that are explained in the AN4158.I assume that tSW, tON_MIN, tOFF_MIN, tOFF_FAST, tFAST_STEP reflect the relevant registers. So:1. Peak current control with auto adjusted decay: - tOFF: th...
Resolved! WBC2TX50 board does not go past FSM_PRE_PING_STATE
I have a WBC2TX50 eval board along with a STEVAL-WLC98RX for testing Qi powe transfer. When I try to make the transfer, the WBC2TX50 board does not go past FSM_PRE_PING_STATE, either with the WLC98RX or with a phone, both of which work with a standar...
Vipergan50TR, switching frequency
Dear ST office, I have a project with the chip Vipergan50TR.We need the output voltage of 20V/0.2A, -20V/0.2A, 7V/1.5A. We plan to let the vipergan chip control 20V channel. I tried your online design tool for AC/DC. When i typed in output voltage ...

STEVAL-WLC38RX transmit data to STEVAL-WBC2TX50
Hi, it seems that the STEVAL-WLC38RX uses STSW-WPSTUDIO and the STEVAL-WBC2TX50 uses STEVAL-WBC2TX50. Is it possible to program the STEVAL-WLC38RX to take external ADC measurements via the NTC pin or the GPIOs and send it to the STEVAL-WBC2TX50 using...

Resolved! Viper53e hardware ?
I have a hardware question about the viper53e chip. For VDD startup voltage, what is the correct voltage to guarantee the mosfet switching will start? I have seen some examples where 11.5V was not enough, and curious to know what the is the best VD...
L6375S (high side driver power switch) function of DIAG1 output ?
I have question about Diagnostic output DIAG1 of L6375S. I measured its behavior when I have open load condition and high VIN+ (when the undervoltage is away). I was changing power supply of integrated circuit from zero to supply voltage , where the ...
Resolved! VN5050AJ CS_DIS not working - again
As in https://community.st.com/t5/power-management/vn5050aj-cs-dis-not-working/m-p/632201#M10745 we now have added seriel diodes for every chip, but it is still not disabling his Current_Sense Output altough the CS_DIS Pin is above 3V. The CS_DIS-1 ...
