When it comes to chips, everyone must be familiar with them. Anything related to electronic circuits relies on chips to run various codes to achieve the desired functionality. Moreover, chips that have been mass-produced for a long time are also quite profitable. For example, when we buy a mouse for 9.9 yuan on PDD, it’s … Read more
Today we analyze a classic microcontroller power supply circuit. The circuit schematic is shown below: ▲ Simplified Switch Circuit Before powering the circuit, the switch “TEST” is open, and the microcontroller is not powered through VCC. At this time, the base of T1 is grounded through R9 (100k), and is in the cutoff state. The … Read more
PMIC Report Summary Chips are generally divided into two major categories: analog and digital chips. Among them, analog chips include analog signal chains and mixed-signal chips, power devices, RF radio frequency devices, and sensors. Power devices are further divided into Power Management Integrated Circuits (PMICs) and power devices. The technologies and application areas related to … Read more
