STEVAL-ESC001V1 circuit schematic question
Hey Community!Newbie here + first postIn the STEVAL-ESC001v1 can someone please explain what this portion of the schematic means/is doing (document attached)?Also how do you determine the max current draw of your Hbridges? Most I have seen just defin...
High-Side Driver application
Hi, In one of our new application, we are using different ST make high-side power switches, to switch different loads at 12V DC (Battery Input Voltage Range : 9V to 16V DC), here is the detailsIs this architecture work switching of loads through high...
Why would STSPIN220 drive power to the outputs at initial power-on?
To ask this question another way, what is expected at the output pins when Vs < 1.5V during power-up?I have a design for driving a linear actuator which uses the STSPIN220. My customer has an issue related to unexpected device power off, and those...
Resolved! Doubt on how to interface a 5V circuit to a 3V microcontroller (STM32) - Input Pins
Hello,The input 1 and input2 signals will be fed from an STM32 but the problem is the signal sent from STM32 is 3.3V but the input to the IC is 5V. How do I convert the same? Please help.
L6470 "blows up" in certain operating mode
We are using a L6470 to drive a stepper. We use the SW-Pin to hold the motor in stop condition. The SW-pin causes a hard stop on falling edge. To prevent the motor from running again also if the firmware would send a run command we provide a clock si...
BTA41-800BRG X-Ray to show an extra die/lead holder in the middle leg.Is this situation normal？
These 5 pcs were mounted on board and test for functional and found 1 component failed then we do x-ray to see what different for good and fail component is.This is x-ray picture of the good and fail component. There is some excess die/lead frame a...
How much current required by the enable pin of the LDK130 / LDK120.
Actually, In our production we are replacing TI's LDO P/N: TPS71701DCKR with ST's P/N: LDK120 / LDK130. With ST part the output of the the LDO are not present even other DC-DC Regulators/LDO which shares same Enable signal, are not able to output the...
