Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
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...
Sir/Ma'am, I have recently bought STGIPS15C60 SLLIMM™ small low-loss intelligent molded moduleIPM, 3-phase inverter - 15 A, 600 V short-circuit rugged IGBT. I have obtained the datasheet of said device however in the datasheet some parameters our mis...
Mass production is normal;There is no short circuit from pins of element;Some resistance are damaged；The voltage stabilizing diode of VCC pin is damaged;The drive signal of the switch tube is normal;The temperature of the switch tube and L6599 is nor...
I’ve made a T-Bot similar to this http://www.buildlog.net/blog/2017/10/the-midtbot-a-new-flavor-of-h-bot/ design. Using stepper motor driver L6470, I can control the movements e.g. up/down, left/right and diagonally using the equations shown here htt...
Hi, I designed battery powered circuit using STC3100 as battery monitoring. I started soldering the prototype and it appears that there is a short between VCC Pin and GND. (Short seen with a multimeter, I did not connect the battery, so I dont expect...
Hi,I'm looking for the solution that can take 5V solar panel input and charge 4.2V lithium battery. I also need to be able to provide the power to the rest of the system even when the battery is not connected. I was looking at SPV1050 IC but I'm not ...
