Category: Diodes & Rectifiers

A Diodes & Rectifiers is a two- lead semiconductor that allows current to pass in only one direction. They can be used in switch mode power inventories and direct power supplies, RF signal demodulation, RF power seeing and veritably much more. Rectifier diode is able of conducting current values varying from several miliamperes to many kiloamperes and voltages up to many kilovolts. Generally, the P- N junction diode is formed by joining together n- type and p- type semiconductor materials. You may find your results or share your thought about to Diodes & Rectifiers by using our Volt.Tech support forums that are supported by thousands of contributing Volt.Tech experts.

Hello,

I want to purchase a wireless charging IC like STWBC86JR, but the data sheet says that it should be within the average frequency of 110kHZ to 205kHZ, so can not I apply it with a resonant frequency of 13.56 MHz? Is there an IC available on that frequency?

Is there a way to design an additional circuit and communicate at that frequency?

Thank you

    Welcome @audrawells, to the community! The STWBC86 is a Qi power transmitter, i.e. it's set to the frequency range100.205 kHz defined in the Qi standard. There's presently no similar power transmitter available for 13.56 MHz, but there are possibilities to transfer and to do wireless charging with NRead more

    Welcome audra wells, to the community!
    The STWBC86 is a Qi power transmitter, i.e. it’s set to the frequency range100.205 kHz defined in the Qi standard.
    There’s presently no similar power transmitter available for 13.56 MHz, but there are possibilities to transfer and to do wireless charging with NFC.
    Does it answer your question?

    The Intel 21154 has( in bytes). Primary write = 88 bytes, read = 72 bytes, Delayed entries = 3 secondary write = 152 bytes. read = 152 bytes, Delayed entries = 3. For the Diodes’ PI7C8154( posted write buffer and delayed sale buffer data size for FIFOs) primary write = 128 128 bytes. Read = 128 128 bytes. Delayed entries = 8. The same for the secondary. therefore the Diodes’ 8154 has further FIFO buffering than Intel.

    According to the hot- exchange specification modification 1.0., the ground should be linked to early power. All other chips on the board should be connected to switched power, which comes latterly, driven from the Hot- exchange regulator.

    The PI7C7300D is" hot- exchange friendly", which basically means it can affiliate to a hot- exchange power regulator. But by itself can not withstand Vcc = 0V and live signals at the I/ O pins-- in this mode, current will flow through our ground. Thus, if ever there's a possibility of this passing,Read more

    The PI7C7300D is” hot- exchange friendly”, which basically means it can affiliate to a hot- exchange power regulator. But by itself can not withstand Vcc = 0V and live signals at the I/ O pins– in this mode, current will flow through our ground. Thus, if ever there’s a possibility of this passing, we require a hot- exchange power regulator and switches for isolation. However, also the less expensive or PI3C32X245 switches are applicable for the signal switches. Most of our guests use this switch in their operations.

    Yes, Diodes manufactures its binary transistor products using separate die which are wire clicked to the lead frames. They aren't monolithic devices.
