Resolved! LDO29300P2MTR
We have implemented the following circuit. This matches the application circuit given in datasheet of LDO29300P2MTR.But it does not yield expected output. We need help!!
WLC38 - compatible chargers
Hi,We are developing a product using the WLC38 as RX.It works OK in combination with wbc2tx50 board, and a single Spigen QI charger we found (no overheating, constant power > 10W achievable).However using any other charging pads (either Qi1 15W or Qi...
Custom Wireless Charger Based on STEVAL-WBC2TX50 - Qi compatibility?
Dear STMicroelectronics Support Team, I have built a custom wireless charger based on the STEVAL-WBC2TX50 evaluation board, following the provided BOM and schematics. I successfully flashed the STSW-WBC2FW_V1300 firmware into the STWBC2-HP controller...
L99DZ100G Out1 to Out6 remains High by default.
I am working on L99DZ100G IC. I am able to communicate with L99DZ100G correctly. But when I check Out1 to Out6 , I am getting 12V by default. If I make on and off CR4.B.OUT1_HS and CR4.B.OUT1_LS respectively it is working correctly. If I make off CR4...
L9369 Drain Source Low Side error
I tried to send a forward message to control the motor. The message goes out fine the first time, but after I turn it off, it can't be turned on again due to a DSLS error. I checked the voltage of the SH and SL pins. SH is 3.8V, and SL is approximate...
[L9369] SYNC5 pin signal
Hello guys, im doing the prj using L9369 and the customer said that they can not provide PWM for SYNC5 pin so could I change to 1 of GPIO pin that received data from PWM to SPI transfer data ? i find out that the input filtering time of GPIO is 2 to ...
L9369's problem shooting
Hello. I'm using L9369 IC and have a problem. Stage A is not working. i made control code for Stage A,B. (they are very similar) i used below two command for H-brdige operation. but. current was not flow. here is phenomenon. 1.Low side GL1,...
Poor PF at light loads
We are designing PFC converter using L6562A controller for 340Vac-440Vac to 665Vdc with 250W as output power.We are facing problems of very low Power factor at lighter loads.What might be the possible reasons for this and how can we tackel this? Rega...
Resolved! About the TS33 series
I don't know the internal structure of the TS3330AMR IC.Is there a functional block diagram of the IC's internal structure?
Resolved! STUSB4710A output not stable
I developed a multi-port charger with multiple STUSB4710A and companion ST1S14PHR with the recommended bill of materials. The evaluation kit worked fine however my board does not work consistently. I read back the status register and detecting underv...
