STUSB4500, how we can set profile through I2C using nrf52832 MCU.
Hello, I am using STUSB4500 Type C IC , I want to set the profile for 5V 3A.I referred the code given in Github:https://github.com/usb-c/STUSB4500Same we have implemented in nrf52832 SDK, but its not getting programmed.Any solution for this? How we ...
VNH7100AS pull down resistor
Hello, do the INA INB and PWM pins have an internal pull down resistor?In the examples you connect these pins with a 1k resistor directly to the microcontroller, but if you do not have a pull down resistor you may be fluctuating at the start of the m...
What do I need to evaluate the powerstep01 ?
We are starting to use your L6470 drivers and used the EVAL 6470H pcb for evauation . I found it very usefull during the development especally being able to see the values in all the registers .It would be helpful if I could do the same with the powe...
What is the reverse recovery time of STBR 3012W diode?
Recovery Time and Pd - Power Dissipation is not mentioned in STBR 3012W diode datasheet.Can you please let me know these parameters?
We want to control and drive a 2 poles 1.5A 12v BLDC motor at PWM switching freq. of 50Khz and 19.000 rpm with a 15cm2 PCB space available. Would you like to recomend the most suitable device set?
We Checked the STSPIN32F0 and the PWM was limited to 30KhHz with overclock, we don´t found any easy way to increase PWM freq.The objective is to obtain the maximum performance of the motor with the minimum heat disipation
STBB1-APUR minumum voltage
Hi,I have a STBB1-APUR in a circuit with a battery. As I can see, it will lower down the voltage from by battery to 3.3V, but it will also boost it to 3.3V if the battery has lower voltage. Is there any way to disable the boost? I would like to close...
Controller for Universal Motor in DC mode
Hello,I want to drive a Universal Motor in DC mode. I am looking for a suitable controller. Can andybody help me?
Overcurrent fault always set without PWM enabled.
I have a 446re nucleo and IHM07M1. I am just trying to get my 6 step BLDC with Hall sensors to work. My overcurrent PIN 'PA6' is set all the time. As soon as i turn on 12 V DC to IHM and USB to nucleo , i read the PIN as HIGH. I have measured the vol...
This is a question about the signal name of VIPer22A.
I am repairing the power supply of AC-DC5V. According to the VIPer22A data sheet, pins 5-8 are "DRAIN" It was confirmed that the purchased VIPer22A has the same pin number 5-8. However, the VIPer22A (4PY138) used for the AC-DC5V power circuit purchas...
VN340SP-E DIAFG signal
Hi,I'm using the VN340SP-E on a board to drive 4 output inductive loads from a 24V voltageIn one condition I connected solonoids (which are actually inductors) to the outputs. I activated the 24V on the output stage and power was applied to the induc...
