Fig. 2：Current direction structural representation of the present utility model.
Embodiment
A kind of new trend controller with power supply automatic switchover circuit is specifically described with reference to embodiments, such as Fig. 1 institutes
Show, the new trend controller is connected with a ground capacity, the positive pole of the new trend controller is connected with metal-oxide-semiconductor one end, the MOS
The other end of pipe and the positive pole of lithium battery are connected, the negative pole ground connection of the lithium battery, one end again of the metal-oxide-semiconductor and power adaptation
Device positive pole is connected.Specifically, the power supply adaptor is 5V power supply adaptors.The positive pole of the new trend controller and metal-oxide-semiconductor
Drain electrode connection, the positive pole of the lithium battery and the source electrode of metal-oxide-semiconductor are connected, and positive pole and the metal-oxide-semiconductor grid of the power supply adaptor connect
Connect.In order to be able to which while adapter works, same charging is also carried out to lithium battery, the positive pole of the power supply adaptor also connects
The IC that charges is connected to, the charging IC is connected with the both positive and negative polarity of the lithium battery.For more preferable protection circuit, the power adaptation
The resistance that the resistance that the positive pole of device is also associated with a ground connection is 100K.
With reference to described in Fig. 2, the addition of metal-oxide-semiconductor and diode to form automatic power supply switching in new trend controller.For
Be better understood from the utility model, it is set forth below under power supply automatic switchover circuit operation principle of the present utility model：
When 5V power supply adaptors not upper electricity, uG=0, uS=lithium battery anode voltage meets uG-uS<0, and | uG-uS |>|
uGS(th)|.Wherein uGS | th | it is cut-in voltage, now PMOS is turned on, power supply is provided by the positive pole of lithium battery completely；When 5V electricity
When electric on source adapter, uG=5V, uS=lithium battery anode voltage are unsatisfactory for turn-on condition, and now PMOS ends, and electric current is through two poles
Pipe is powered to new trend controller, and now power supply is provided by power supply adaptor completely.
Because lithium battery circuit is constantly coupled on new trend controller, PMOS during in order to prevent that 5V power supply adaptors are not upper electric
Cut-off, causes dysfunction.Diode is additionally provided between the new trend controller and power supply adaptor, " is unidirectionally led using it
Electrically ", it is ensured that the function-stable of circuit.
The utility model still has a variety of specific embodiments.Institute formed by all use equivalent substitutions or equivalent transformation
Have technical scheme, all fall within the utility model it is claimed within the scope of.
