We bought the following evaluation boards to test a wireless charging concept:STEVAL-WBC86TXSTEVAL-WLC38RXNow it seems that the datasheets of the evaluation boards and also from the chips that they use got pulled from the website. The control softwar...
STPM801 NC and TIE0 pins - connect to GND or leave floating
Hello I am using a STPM801 eval board and will design in the STPM801 on my power management board. I am confused by the connections to the TIE0 and NC pins as described by the STEVAL-STPM801 data brief document and the app note AN5830. The data brie...
Resolved! Will STWBC86 and STWLC38 Work with 3rd Party Qi Chargers/Receivers?
Hi everyone,I'm currently working with a wireless charging system using STWBC86 (transmitter) and STWLC38 (receiver) from STMicroelectronics. Both chips are based on the WPC Qi standard and are designed for wireless power transfer.I have a few questi...
Resolved! LED1202 Address Pins
I notice that in the schematics for the STEVAL-LLL007M1 STEVAL-LLL007V1, part of the evaluation kit for the LED1202, several of the A0 pins for the attached LED1202s are pulled to ground with 10K resistors. However, in the datasheet for the LED1202 ...
Are WBC86TX, WLC38RX discontinued?
HelloCurrently, all information on WBC86TX and WLC38RX has disappeared from the ST homepage.Does this mean that the two chips are discontinued?I would like to know whether they should not be applied to new designs,and how long they are planned to be ...
Resolved! SPV1050 Temperature Range
Hi."Does STMicroelectronics have any plans to release the SPV1050 with an extended operating temperature range suitable for automotive (e.g., –40°C to +125°C) or military-grade applications?"Best Regards.
Revision code on STUSB4500
We have a batch of chips labelled M27400 and another marked M37400. Does this marking indicate the version number of the chips? I'm seeing a difference in behavior between them (the M34700 are reporting PE states I haven't seen previously). Thanks,
Resolved! STDES-2KW5CH48V
Hello,We are working on building 48V Lithium battery charger for AGV's. I would like to know if below Eval board from ST is available for purchase. STDES-2KW5CH48V2.5 kW - 48 V battery charger reference design for industrial light electric vehicles (...
Resolved! Clarification on Maximum Voltage Limitation of EVLSTGAP3S6S Board
I am planning to purchase the EVLSTGAP3S6S evaluation board for my research. While reviewing the datasheet, I noticed that the board is specified to support a high-voltage rail of up to 520 V, limited by the MOSFETs and capacitors. However, I observe...
