Diode as a temperature compensation circuit for transistors
Both diodes and transistors are made of silicon. As the temperature T increases, the transistor Vbe decreases, ib=VCC-Vbe/R7+R5 ib increases
To power a TLC555, use TL431 to make a small power supply. The schematic diagram comes from the TL431 chip manual.
How to calculate the output current of this power supply
This section answers the hot questions about the hardware composition of PLC, which will be of great help to the actual wiring installation operation in the future. 1. Q: What is the hardware structur
