Power management

Using the VNHD7012AY development board to run a brushed 12V motor, I have trouble at initial startup trouble that appears to be a problem with the fault circuitry.

Picture #2: (Current waveform) Operation with resistance added to OUT linePicture #1: (current waveform) Picture when motor does not start Regardless of what values I install for gate resistors (0, 475, 1100 ohm), Vref resistors (8-40K) adding ext fi...

Question about STPM01 not reading 0 at no current. (See details)

Hi!I have a couple of questions regarding the STPM01 energy metering circuit:We are using it for measuring currents only with Rogowski coils. (We have 4 circuits on our board).We are not using the voltage measuring, so it is not connected.The microco...

Max load on output of STEVAL-ISC005V1

Hello, What is the max load I can put on STEVAL-ISC005V1? I mean, I try to load 100W on PD03, setup to 20V/5A, with an electronic load but something burn on the evaluation board, I thing I make something wrong. Could somebody help me with this topic?

TD350E - interpreting date/batch codes and desaturation sensitivity

I'm presently debugging an intermittent desaturation issue in a stable product platform (stable as in 10+ thousand units over more than a decade).From what I can tell so far the TD350 device is signalling a desat on occasion without a reason I can ob...

The data sheet for the SCR BTW67-1000 is not clear as to which pin is the gate. The diagram shows a pin to be parallel to the centre line of the mounting holes but on the device there is no pin as such. Is the smaller pin with a smaller hole the gate? A

We use the LD1117 and we notice that the Rthja is higher for the SOT-223 that the SO-8; it seems counter intuitive since the SOT-223 is looking more a power package than the SO-8. Please explain? Denis Lachapelle eng. Cysca.ca

How to munt and cool D2PAK IGBT in power bridge

I want to use  STGB8NC60KDT4 IGBT, 15 A 600 V, 3-Pin D2PAK (TO-263)in a motor controlpower bridge, The bridge will be running at 300VDC and about 3-5 amps. At this power there will be 6-12 watts dissipated in the IGBT.I would like to cool them by scr...

We use the VNH3SP30 H-bridge motor driver for an application where we need to drive a motor with peak currents over 30A. The PCB layout are made following the recommendations from datasheet. But the H- bridge die when running the motor. Any help?

Is external protection needed?And what type off protection if it also should be able to handle EMC Burst and Surge pulses?
