L7987L Failure
Hi, we are using L7987L IC top generate -15V from 24V input. However, we see repetitive failure in the IC. I have attached the waveform also (Green- Input Voltage, Pink- Vout). I am also sharing the layout for the same. Switching frequency we have ke...
L6470 Step motor driver and VS caps run hot even when bridges are in HiZ
I have a custom board that uses the L6470 for driving step motors. All motor functions are working fine. Circuit attached. Picture attached.What I have noticed and concerns me is that in instances where the motors are off or not even connected the ...
STEVAL-DPSTPFC1 source code and BINARY code
hello,I have STEVAL-DPS334C1 and STEVAL-DPSTPFC1. I am trying to put PFC code on STEVAL-DPS334C1 again. I load bin file via stm32programmer. then STEVAL-DPS334C1 crashes. I need source code to find where the error is coming from. Or if you have any s...
STEVAL-DPSTPFC1 Hardware Problem
Hello.When I measure between 5V_SCR1 and GND_SCR2 in STEVAL-DPSTPFC1 Hardware, I see 9V. And when I start via Switch, it goes into standby mode when the output is unloaded and reaches 300V. It never becomes 400V. I quickly turn the switch to the off ...
VN5E006ASPTR-E spice model
Hello, This VN5E006ASPTR-E FET has unencrypted spice model? Thank you.
Motor acts as generator and damages VNHD7008AY
We use the VNHD7008AY to control the motor of a cargo lift. The lift has an emergency switch, which disconnects the battery from the circuit.In case of an emergency cutout, the lift runs down while its motor generates a high voltage, which finally ki...
Resolved! LDL212PUR LDO ceramic caps and resistor values
Hi,I want to buy LDL212PUR LDO. I have 2 questions:1. Can it work reliably with ceramic capacitors?2. What are the recommended resistor values for voltage adjust version?I cannot find this information in the datasheet.Thanks,Adam
Resolved! About the TS3330AMR
The TS3330AMR has a voltage reference, but the internal configuration of the IC is unclear.Is a reverse bypass diode, like the reverse voltage protection of a linear regulator, unnecessary?
Resolved! WLC38 + STWBC86 - 5W Reference Designs?
So it looks like there are 2.5W or 15W reference designs, does anyone have a 5W reference design?
stspin32g4 buck converter for Vbat 15V (4s)
hello comunity,i want design a motor controller with the stspin32g4.i have a question about the build in buck converter:i want use the stspin32g4 just with a 4s battery ca 15V and a 2 wire control ifc (servo pwm + ground).I want the stspin32g4 genera...
