Utility model content

The utility model is mainly solving the technical problems that provide a kind of practical electric car car-mounted electronic device power supply Low power architecture, can realize under electric car car-mounted electronic device holding state almost zero-power with simple architecture.

In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of electric car car is provided Electronic device power low power architecture is carried, including：Normal power supplies module, low power consumption control module, the normal power supplies module bag The protection modules such as clamper surge, LDO are included, the low power consumption control module includes the first MOSFET, the first diode, the two or two pole Pipe, the 3rd diode, the 2nd MOSFET.

In one preferred embodiment of the utility model, the protection module such as described clamper surge include TVS clamp circuits, from Recover fuse, Support Capacitor, anti-circnit NOT, common mode rejection circuit etc..

In one preferred embodiment of the utility model, the LDO is converted to electric car car including vehicle low-tension supply The serial of power supply needed for carrying electronic installation is changed and protection circuit.

In one preferred embodiment of the utility model, the low power consumption control module includes the first MOSFET, the one or two Pole pipe, the second diode, the 3rd diode, the 2nd MOSFET, the protection circuit such as the first MOSFET the second end and clamper surge Output end connection, the first MOSFET the 3rd end and LDO input connects, the first MOSFET first end and second MOSFET the second end connection, the 2nd MOSFET three-terminal link ground wire, the negative electrode of the first diode and the second diode Negative electrode, the negative electrode of the 3rd diode are in parallel, and are connected with the 2nd MOSFET first end, the anode connection key of the first diode Spoon signal, the anode connection rigid line wake-up signal of the second diode, the anode of the 3rd diode is connected with MCU.

The utility model has the advantages that：

1st, to low power consumption control electricity by the way of key signal, rigid line wake-up signal are in parallel with MCU dormant control signals Road is controlled, and can a variety of demands be realized with real-time wake up；

2nd, low power consumpting controling circuit is connected between protection circuit module and LDO modules, when electric car is filled with vehicle electronics Put and almost zero-power can be achieved under holding state；

3rd, electric car is with after car-mounted electronic device power supply normal work, by electric car with car-mounted electronic device autonomous control again On the opportunity of secondary entrance dormancy holding state, realize the function of delay cut-off.

Brief description of the drawings
