Power management

Working with the PowerStep01 and have run into a question regarding the minimum tick clock speed input. The documentation seems to indicate 4MHz but I can not find a min value.

The purpose of this is to determine if I can run the motor slower than approx. 15 steps/s which is the slowest possible with a 4 MHz tick. This is at the maximum microstep of 128. Considering a change to STSPIN220, lower current and voltage spec but ...

Monitoring ISB039V1.

Hi,We are researchers trying to use the ISB039V1T for an inductive charging application. In the past, we have worked with ISB045V1T and used the STWBC GUI with the STEVAL_WBCDNGV1 to flash firmware updates and monitor the board's charging status. How...

Need simulation software for the SG 3525A

No Output from EVALPWD13F60 board

We applied VCC1 & VCC2 @12V , VS = 110V, HIN1=3.3V, LIN2=3.3V (HIN2=GND & LIN1=GND) Measured output voltage across OUT1 & OUT2. However, no output voltage is observed. And also tried HIN2=3.3V, LIN1=3.3V (HIN1=GND & LIN2=GND). Here also same no outpu...

EVALPWD13F60 PWD13F60 only output pulses and not a permanent output

Hi Im using EVALPWD13F60VS = 100VVCC = 8VHINx and LINx = 3.3v  GND = I connected the GND of my 100v supply, the microcontroller GND and the 8v supply GND.Output 1 to Output 2 = 5k resistor   The problem that I'm facing is that I can only get pulses o...

We are using EVALPWD13F60. We are unable to make motor turn on.

We are using EVALPWD13F60. We are unable to make motor turn on. While we give pwm(10KHz) to HIN1 and LIN2 with different duty cycles by putting LIN1 and HIN2 as low , we getting 6 V as output. When we give HIN1 and LIN2 full time high voltage is drop...

Using STEF01 UVLO below recommended voltage 8V?

By resistor calculation and also by given graphic it is possible to adjust UVLO voltage as 4.5. However, in datasheet, it is written that using UVLO below 8V is not recommended. What happens if UVLO threshold used as 4.5 V?

How do I get 60W profile from STUSB 4500 ?

So i need a sink setup with the standalone stusb 4500 but i can not find examples on how to make a 20v 3a setup for negotiation. Anyone who could bring some light into this ? Maybe you have a schematic you could share so that we all can find or is it...

Spice Model for STW15NK

Hi,I tried to use the spice model for the STW15NK (.subckt) but it dosn't work with LTspice.I imported the .subckt with LTspice without any error.But the FET don't torn on/off with the input signal on Gate.Any known issues?thanks,Martin

VNH5019A-E gets damaged while hot plugging with motor, as we disconnect the motor when it is being driven by this H-bridge. Kindly find attached schematic. We require your valuable feedback in this regards. Thank you very much.

We are using VNH5019A-E to drive an actuator. We have followed all the schematic mentioned in evaluation board of VNH5019A-E for the system. We have a case when we have to disconnect the motor while this H-bridge IC is driving it. In this scenario of...
