Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
The datasheet for the LD1086 specifies that I should use a 10 uF capacitor to filter the input/output of the device. The datasheet schematic for a typical application shows polarized filter caps. But the datasheet doesn't specify what type of capacit...
Hi, I need to know whether do you use Viper 22L component? Please respond......
Hello,Since I'm trying to design a relatively simple and mainly small STM32MP157FAD1 board (MPU, DDR3L, eMMC, WiFi+BT, microphone, speaker and display), something like a wearable motherboard, I'd like to ask if it would be possible to power the whole...
We have received a part from ST Microelectronics. Kindly provide us with the date code and lot code information for the below part number. I have attached images of the received part for your reference.
I have a product with replaceable battery (1S1P) , that can be changed by the user.User can put primary battery (non-rechargeable) 3,0V or rechargeable battery (3,7V).The rechargeable battery will be charged outside of the product. So the battery wi...
I have made a custom pcb of STEVAL-ISV019V1 circuit. In that ,we need to charge 3.7v lithium ion battery via USB supply and solar panel. When I connect USB supply or panel voltage as input voltage the complete input voltage is coming in the bat...
Hello,We are using the SPV1050 charger for our device, and we are planning to certify our device with FCC standards, so can you please advise some recommendations on the PCB design to fit the FCC requirements? Also, someone recommend me to use a se...
Today I received several of my LED2000DR based LED boards. Everything worked flawlessly when using the chip as a plain LED driver. However, after trying to feed a PWM signal into the DIM pin the dimming worked for about a second but then the board we...
Hi, I have a requirement to drive a Triac from the MCU powered by a DC/DC converter. The AC supply is typ 24 VAC @ Rc terminal with respect to C terminal. The Triac is to be driven as attached. The MCU GND should always regulated at Rc - 3V3. The MC...
