Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
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...
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...
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...
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 ...
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.
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,
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 (...
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...
Application : We are developing a AC switching circuit using dual MOSFET configuration. The application is for driving the 208VAC, 480VAC, 40A AC heaters to control its temperature.1. Is it preferred to use MOSFET or IGBT for this?2. Which MOSFET ser...
Hello All,I am using L7987L to generate +15V from 24V. I have 10 same boards wherein I have used the same circuit (see below), I am able to generate 15V for 2 boards but in rest it is generating 1.22V only. R191 is 6.8kohm and diode D36 is US1M-E3/61...
