Power management

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...

Should a inductor be added between Cin and the drain of MOS in the applicaion of Liner Voltage Regulator in L9779

 I've got a problem about the engine management IC——L9779. I would really appreciate that if you could help.Here is the thing：  A Liner Voltage Regulator has been built on this chip, which could transit the voltage from 12V to 5V and 3.3V.And this Re...

STEVAL SPIN3201 Hall Effect RPM Stability 3000RPM +/- 1.5RPM

Dear CommunityI have developed a BLDC motor drive with a senorles BACKEMF control using a DRV10983 IC.It uses sensor less control no halls used. If I look at the motors hall effects that are not used on the DRV10983 Chip My issue is that the speed is...

I'm trying to do a battery charger using L6566BH component. Is there an application note on how to regulate the battery current using L6566BH chip? Thanks
