Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
To confirm, the max output voltage on CS pin (I assume it is called VSENSEH) is 8V according to Table 8 on p11 (https://www.st.com/resource/en/datasheet/vnd5e006asp-e.pdf). But I assume this depends on the sense resistor and ISENSEH of 7mA. What is...
hello everyone,In a battery-powered IoT project, I can never make accurate measurements because my battery voltage is the same as my reference voltage. I did not use any power ICs to reduce the cost of my project.I am using a 3.6V li-soci2 batterySav...
Hi,STPS3045CPI is now obsolete and STMicroelectronics no longer carries collateral support. I am wondering if anyone can help. I am looking thru old documentation but it is not clear to me whether the mounting plate on the top is connected to the com...
hi,I am now familiar with the STPM3x programming, by using EVALSTPM33/34 boards.I have been able to do some basic low voltage testing where I receive interrupts on INT1 line on EVALSTPM33/4 for voltage swell before I try mains voltages.Then I run the...
We are developing an OEM board which is capable of driving bipolar stepper motors from 15 to 80Vdc 10A max, in voltage mode and current control. Our customers should be able to change the supply voltage (Vbus), operating mode (voltage or current), wi...
In my 750W PFC project, I've employed the L4985A PFC controller IC. I utilized the e-design suite offered by ST to design my PFC, and I fabricated the PCB using the components specified in the e-design file. Despite ensuring that all the necessary v...
Hi, can you tell me what happens to the LDL212 when the input voltage drops below the output voltage+dropout? Does it track the input voltage (minus the dropout voltage)? Or does it drop out? Also, in the datasheet it mentions undervoltage lockout in...
I have tried every possible option to get the discovery kit working. I am not satisfied with your technical support. How do I return item for a refund?
Hi All,I have been stuck for a week with this.7I can read and write to the registers of both L6470 correctly.And I can also send commands properly to L6470 via the SPI from STM32F407 discovery kit.However, when I try to start driving the motor, the m...
When using the chip GIPS30C60-H, sometimes the three-phase bridge switching signal is given but there is no output, regardless of whether the SD/OD pin is set high or not. This chip is used in a motor controller with a 0-270V DC bus supply and input ...
