STC3117: SOC level of Ri referred to by datasheet

For calculating the VM_CNF value the datasheet of the STC3117 gives the follwoing equation:VM_CNF = Ri * Cnom / 977.78,where Ri is the impedance of the cell.The impedance of the cell however depends on the SOC, so i wonder at which SOC the Ri is supp...

Hi, As a part of our new product, we have decided to run the product on PD capability. So, we have decided the product to be developed with two USB PD ports, so that one port can be used for Wall PD charger and other port for PD by laptop.

We have decided to use STUSB4500 for stand alone PD controller, But the main struggle is to coordinate these two PD ports and switch between them as availability.Priority is given for Wall charger PD port and the other port is used for PD when Wall c...

Hi, where finde, and decode date of production for triac BTA12-600BW and other triacs in TO-220 package?

LD1085D2T33R 5V INPUT TO 3V3 OUTPUT IS SUFFICIENT ARE NOT

Hi,  In our project, we are using LD1085D2T33R as this regulator. In this regulator voltage drop is 1.3V .but in our design we providing 5V input the output is 3.3v it sufficient are not please let me know.

Do you have a safety data sheet for Real-time clock and TIMEKEEPER, SNAPHAT M4T32-BR12SH6. Could you provide me this document, Thanks

L6387E maximum gate drive current?

Hi,We are using a L6387E to drive two half-bridge MOSFETS of type STW20N65M5 or equivalent in a off-line DC/DC converter.The circuitry in between consists of a 10 Ohm resistor, and a diode+3.3 ohm resistor in discharge-direction, in parallel respecti...
