Troubleshooting with spv1040 panel shunting

Hi!We developed a device using the SPV1040 as a DC-DC converter connected to the PV panel (5V MPPT 0.150A sc)When the no-load voltage of the panel is less than 2 volts, but the same panel when connected to the converter produces a much lower voltage....

Why do the output of the bridge rectifier shoot above 1KV when an inductor is placed as a filter in series with it?

Hi,I am designing an inverter using ST's application note AN2794.I have customized the application note which was designed for 1KW power to 1.65KW.The problem i am facing now is that when i probe the output of the bridge rectifier placed at the outpu...

Hello, I am using three L9942XP1TR driver ic for controlling three stepper motor.

The spi communication is interfaced to driver ic from raspberry pi(.Interfaced with raspberry pi using I2C for my project.The 3 gpio pins MCP23017(pin8,21,22) drives the enable pin of 3 l9942xp1tr(U3,U4,U5).Please refer image.While programming, after...

What is the default power on value of config register for L6480 stepper motor ic

In the March 2015 datasheet it says that the hex reset value for the config register is 2C88. When I try this on my actual devices (4 of them) I get back 2C08. Based on the value this means that the OC_SD bit is set to 0 - Bridges do not shut down (...

I am using STM6601CA2BDM6F push button controller in one of my device development projects. I would like to know if I can use this IC for delayed shutdown.

Changing the MOSFET on X-NUCLEO-IHM08M1 to STP110N7F6.

Dear All,​I changed the MOSFETs on IHM08M1 to STP110N7F6 and modified the settings of dead time of Driver and Mosfet in MC work bench. But the BLDC can't run well(it doesn't reve-up often) . The manual of MC work bench only indicate user to modify mo...
