Which footprint do we need to consider for STL6P3LLH6? Whether its Type C or Type F?

Could you please let me know, which land pattern do we need to consider for  PowerFLAT 3.3 x 3.3 package,for STL6P3LLH6? Whether we need to consider  Type C or Type F package? The data sheet doesn't clearly say which is defined by what and neither do...

L6480H Stall Detection - Does It Really Work?

I'm trying to evaluate if the L6480H stall detection actually works. We have been using the L6470H and we proved that stall detection with that chip did NOT work properly.I bought the EVAL6480H and STEVAL-PC0009V2 boards with the hope that I could pr...

L4970a Output Oscillates

Posted on March 04, 2014 at 09:46I need the following: 24V vehicle input. Allow for 28V. 13.8V @ 10A output. I used an L4970a. My circuit delivers the load, no problem.On initial switch on with no load, the output is stable. When I place a load up t...

RHFL4913A datasheet short circuit current vs. Rsh

Section 7 Typical Characteristics of the RHFL4913A datasheet contains Figure 44 and Figure 45. These figures state the output voltages used to generate the plots but don't mention the input voltage value. Can we assume that the input voltage is 2.5V ...

How to reconfigure STEVAL-ESC001V1 to hall inputs

The gui allows reconfiguring to HALL inputs, which is why we purchased these boards. To test some motors during fast startup using hall sensors.When setting up HALL inputs there appears to be no valid pin configuration to get the sensors connected. D...

I want to know whether VN1160(TO-252) part is obsolete or still in active?

L9826 - In SPI communication what should be the CPOL & CPHA setting of Master Micro controller for the proper communication with Slave L9826.

 In the datasheet it is mentioned as "The 8-bit command data are transmitted into L9826 shift registers every CLK falling edge". So which means the master uC sends out the data for every falling edge of the clock and the Slave L9826 samples this data...

Viper37LD - does not regulate output voltages

I'm using Viper37LD in my project with the following features:Vin: 85-270VACOut1: 12V-1.5AOut2: 15V 0.125mAI used eDesignSuite to calculate component values.I have some boards mounted and I have the following situations:1- The source does not regulat...

STEVAL-PCC009V2 + EVAL6480H with cSpin and minimum wait time between sending the cSPIN_Set_Param() command (IAR C/C++ IDE)

Dear all,after some time I'll be able to correctly run the demo applications that came with the cSpin firmware libraries (search about STSW-SPIN005 on the ST site).The first part of this post is about how to set the demo design and compile it, the la...
