Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
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 ...
Due to a number of hardware constraints, I need to specify ADC3 for the phase current, bus voltage and temperature feedback for my ST Motor Control Workbench 5.2.0 project for a custom brushless control board. However, I don't see way of specifying ...
Hi,Can we have some more data for L9758? Datasheet provides very less information. Typical application schematic (external components values/part numbers)Typical performance characteristicsStart-up, efficiency, shutdown, load and line transients wave...
BQ25120 SYSout voltage return to default value after a few sec of configuration via I2c.Observation: The SYSout voltage won't drop if we constantly read the system register(0x06) valuevia I2cHere is our register configuration.#define BQ25120_SLAVE_A...
Hi,Can we have some more data for L9945? Datasheet provides very less information. Some timing waveforms for all 8 channels(or may be only one channel, which can be replicated for the other 7 channels). Functional block diagramTypical application sch...
I recently purchased these from element14: https://in.element14.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=91&urlRequestType=Base&partNumber=2797963&storeId=10186.The ones I got show this as the chip marking: https://i.imgur....
