Electronic speed controller for Drones
I'm designing an ESC for a drone. I found STM's UM2197 design document. I have a question why this DC link capacitor design uses 2 Capacitors in parallel (P/N 35ZLH330MEFC10X12.5) of Rubycon.This capacitor has the following parameters: Ripple Current...
Resolved! Minimizing Current Consumption in High Voltage Divider Circuit
Hello everyone,I'm working on a circuit for monitoring the bias voltage of a GM tube, which requires a high voltage of 100V. I am currently using a OA1NP22C op-amp configured as a unity-gain buffer to read the divided voltage. To minimize current con...
How to sense Analog input from a Pin in STEVAL-TTM002V1?
I am usingSPC5 IDE with STEVAL-CTM009V1 (Eval Board) and STEVAL-TTM002V1 (Control Board), but not aware how to sense voltage from set of analog input pins (43). In STCubeIDE, it automatically gets generated after pin config, but in SPC5 its not gett...
Resolved! VN9D5D20FN frequently setting SPI error bit in global status byte, datasheet not clear on cause
I am controlling a VN9D5D20FN high side driver with the SPI2 interface on an STM32F373. I can communicate with the high side driver, and sometimes briefly get an output to turn on using SPI control. However, frequently the high side driver sets the...
EVAL-L9963E-MCU firmware & drivers
I am a master's student and working on BMS and I want to use EVAL-L9963E-MCU evaluation board for my research work. But I am not sure whether the firmware or driver for this evaluation board is available in the ST website. Please help me with this in...
L9960 pcb design
Hey,I'm planning on building an ETC to control a throttle valve using the L9960 H-bridge. I'm currently in the process of designing a PCB for it. The driver is supposed to have 12V as VsV_sVs and handle up to 10A max as output load. The PCB I'm des...
Resolved! What's the maximum output current of STLD40D?
Hi Sir, What's the max output current?There only shows the min current 20mA of Io.Thank you.@STLD40D@Led
Resolved! Is the PD85004 part discontinued?
Is the PD85004 part discontinued? We wonder if you have any remaining stock to make the power module with that part.And I was wondering if there are any parts or subsequent parts that are an alternative to that.
L298N and L297/1: low-pass filter usage
When using L298N and L297/1 Is it necessary to use a low-pass filter when connecting the L298N current detection terminal to the L297/1 sense?
Schottky Diode for GHz range
Hi, I am working on a project involving input signal in the 3-5 GHz range. For the rectifier circuit, I wanted to use the BAS70-04FILM diode by ST. Is that suitable for the given frequency range though? Else is there any alternative for the same? Th...
