Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hello, I am studying DC-DC converters, power optimizers for grid-connected PV.I saw some work with the SPV1020, but it seems to be discontinued. Do you know why? Is there a new version?I would also be grateful if I indicated any evaluation module, th...
I am currently using the X-NUCLEO-IHM15A1 Shield with the NUCLEO_F401RE MCU board to evaluate the use of the STSpin840 Motor driver using a single 12VDC motor. During the programming and debug process the motor will automatically start turning. Beca...
I am currently designing a PCB that will control a single motor using the STSPIN840 (X-NUCLEO-IHM15A1 Shield). The datasheet is pretty good about explaining how to connect things if you want to run the outputs in parallel mode but it neglets to tell...
We are trying to set up a L6472 for step mode control using the STCK pin with limited success. Here is our setup of the registers.CONFIG: 0xFE80Status: 0xFE02STEP_MODE: 0x1CWe are trying to drive the STCK pin with 3.3V LVTTL from a PIC32 at 1250 Hz.T...
I am trying to replicate the circuit given in application note AN2097 which is a 10W SMPS at 12V.I am stuck 5 ohm NTC used in the circuit. Can you tell me the wattage of it. It is very expensive also, please tell me any way to replace it. Please find...
We know that. when using three hall sensors, the 3 Hall sensors should be spaced across the printed-circuit board (PCB) so that they are 120° electrical degrees apart. From the center of the motor axis, the number of degrees each sensor should be spa...
DEAR Sir/MamI have purchased your X-NUCLEO-IHM07M1Three-phase brushless DC motor driver expansion board based on L6230 and i am driving this by using lpc2138 evaluation board.Now the problem is that i can't find any input data for driving this motor ...
In the datasheet of the L7987L there is an application schematic for a negative converter (p36), here the VCC is connected to VIN with a 10 Ohm resistor and a capacitor to the generated negative rail (I guess is to filter the power for the low power ...
I'm trying to work with the STSW-SPIN3202 6-step firmware example for the Keil MDK, specifically the potentiometer example. I opened the firmware and in the infinite while loop I have MC_StartMotor() as per the instructions listed in there. But nothi...
Table 1, Pin description, on page 3 lists pin number 1 of DFN6 on GND row with a description of "Output voltage". It should be combined with pin #3 on Vout row.https://www.st.com/content/ccc/resource/technical/document/datasheet/group3/df/64/f9/b7/91...
