Embodiment 2

[0027] The charging integrated chip IC1 uses the CN3058 charging management circuit to charge the Ni-MH battery or the Ni-Cd battery E1. The peripheral uses very few components, and the inside actually has a current-expanding power transistor, a thermal modulation circuit, and an automatic current control circuit. When the power consumption is relatively large or the ambient temperature is relatively high, the temperature of the chip is controlled within a safe range. The charging current is programmed by the external third resistor R3, and the charging voltage selects the different voltage drops of the diode D1 to meet the needs of two Ni-MH batteries. The input terminal complies with the USB bus technical specification. Power consumption of the sleep mode, the current consumption of the battery is less than 3 microamps. The invention adopts a plug-in switch, and when the mini USB plug is pulled out, the battery is separated from the circuit, and the current consumption is ze...

Abstract

The present invention discloses a multifunctional charger which comprises a socket, a mobile phone charging module and a mobile phone charging interface. The output end of the mobile phone charging module is connected with the mobile phone charging interface; a battery charging module and a battery are arranged between the socket and the mobile phone charging module; the socket is connected with the input end of the battery charging module; the output end of the battery charging module is connected with the battery; and the battery is connected with the input end of the mobile phone charging module. The multifunctional charger has the advantage that the battery charging module is used for charging the rechargeable battery under the condition with an external power supply so as to emergently charge the mobile phone under the condition without a power supply; the battery charging module can charge the battery when the mobile phone charging module charge the mobile phone; under the condition without an external power supply, the rechargeable battery with electricity storage can charge the mobile phone through the mobile phone charging module, or the dry battery can directly charge the mobile phone through the mobile phone charging module.

Description

technical field [0001] The invention relates to a charger, in particular to a multifunctional charger. Background technique [0002] One of the existing mobile phone chargers is an AC mobile phone charger, which uses 220V alternating current to charge the mobile phone after voltage conversion. Sometimes people run into the situation that the mobile phone is out of power when they are working in the field, traveling or traveling on long-distance vehicles, and these places often have no AC power supply, so there will be an embarrassing situation that they cannot communicate. Another kind of mobile phone charger is to charge the mobile phone after the battery is boosted. Because it uses a boost circuit, the battery-type mobile phone charger can use a battery with a lower voltage as the power supply. The battery-type mobile phone charger solves the problem that the traditional charger must be charged under the condition of alternating current, and has certain advantages. The b...
