CTR1 for microcontroller IO switch to power a 5 v chip high levels low electricity at ordinary times switch

CodePudding user response:

Theory, do not recommend using this, need to pay attention to the point where there are multiple,

If you want to control it is recommended to use, XC6219, model of this belt control pin,
Or in MOS tube, the pressure drop is small, simple also,

CodePudding user response:

Problems and phenomenon is not working?

CodePudding user response:

The switching circuit is no problem, you can output the control signal is 0, 1, but as a power source is wrong, think after 10 k resistor, what is the ability to drive, the most basic of the output should be out of the emitter, 1/f, said makes sense, commonly used to control the power on and off PMOS, can search the relevant circuit

CodePudding user response:

Justified on the ground floor, can use the nmos, reference notebook motherboard isolating circuit

CodePudding user response:

Xc6206 output is a bit weird, all the way power respectively to two modules, are generally in the past, directly add filter capacitance, respectively, at present had not seen this kind of usage

CodePudding user response:

The basic level can't give you the circuit power supply, power supply ability is very weak, can recommend you two methods, 1. Before the class into a mosfet, (2) into a generation of enabling functions "or DC/DC.

CodePudding user response:

Power series as long as notice is equivalent to the 11 k resistor, busywork is very big,

CodePudding user response:

I usually use the electricity, M1_POWER microcontroller IO port, VCC power supply
