Although the use of emitter current limiter resistors looks good and technically correct, a simpler and a smarter approach could be to mount the BJTs over a common heatsink with a lot of heatsink paste applied to their contact surfaces. This idea will allow you to get rid of the messy wi...
it should be cleared of all kinds of maintenance tools on the spot and the application of maintenance, check whether there are other items left in the frame of the switching power supply machinery and equipment, such as gong wire knife, moving hand, etc., in order to prevent unnecessary sho...
The level shifter consists of one discrete N-channel enhancement MOSFET for the serial data line I/O and one pullup resistor on each side. The gate (G) must be connected to the lowest supply voltage VL, the source (S) to the bus line of the "lower voltage" side, and the drain (D...
three terminals, but this time they're named source (S), drain (D), and gate (G). And again, there are two different versions of the symbol, depending on whether you've got an n-channel or p-channel MOSFET. There are a number of commonly used symbols for each of the MOSFET types...

section, but with a few alterations to accommodate a typical 1-Wire bus. By placing the lower-voltage device on the N-channel MOSFET's source, a 3.3V system can be integrated with any other system regardless if it operates at a higher or a lower voltage, as shown in Figure 2 and ...
A key advantage of the MAX12900 is that it can convert PWM digital data from microcontrollers that do not have a dedicated DAC output into a current signal over a 4–20mA loop with 2-, 3-, or 4-wire configurations. This is equivalent to an ultra-low-power, high-resolution digital-t...
usually sits beneath the flight controller and connects via a wire harness. However, if one ESC is damaged, you’ll need to replace the entire board—a trade-off between risk and convenience. However, 4in1 ESC nowadays are highly reliable so it’s generally not something to be concerned ...
The analysis is focused on the charging and discharging of a transistor gate, and on the impact that such operation has on EMI. The ST L9945, an 8-channel configurable HS/LS pre-driver, is considered as the reference device to be used in several applications (P&H, H-Bridge,...
Due to the different working voltages of the load box, two kinds of MOS tubes are required. For dc28v, n-channel enhanced FET | rf540n is selected, with a maximum withstand voltage of 100V, a maximum working current of 33A and a maximum power of 130W at room temperature (25 ° C...
