Resolved! L7987 ripple issue
HI Sir，we have two different results of the ripple noisebase on same PCBA design, but different L7987 origin:1. Mark of "ST e3 G9207，L7987， CHN 3L0"，ripple noise 2.2V 2.9KHzinput 24V， output 12V， load 5ohm 2.4A 2. Mark of "ST e3 7B658， L7987， PHL 037...
Resolved! STPS3045CPI Obsolete - Common cathode doubt
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...
Resolved! STPM3x INT1/2 outputs - how to configure
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...
Resolved! Use of powerSTEP01 in “voltage mode�?
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...
L4985
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...
Resolved! LDL212 undervoltage mode
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...
Steval-L99615C Request Refund
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?
L6470 eval board X-NUCLEO-IHM02A1 give error thermal shutdown and warning status
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...
Why my STGIPS10C60-H has no output voltage
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 ...
STDES-2KW5CH48V
Hello,We are working on building 48V Lithium battery charger for AGV's. I would like to know if below Eval board from ST is available for purchase. STDES-2KW5CH48V2.5 kW - 48 V battery charger reference design for industrial light electric vehicles (...
