Embodiment
The invention will be further described below in conjunction with embodiment.
As shown in Figure 1, a kind of heating integrated module driven by battery, the following circuit of module integration: line with heating function circuit, charge mode testing circuit, battery charging and protective circuit, LED driving circuit;
Line with heating function circuit (C1) is as driving the electro-heat equipment of being located at module-external, and electro-heat equipment produces heat;
Charge mode testing circuit (C2) detection module is in battery charging mode according to user or normal glow mode;
Battery charging and protective circuit (C3) provide lithium battery or rechargeable battery charging and battery protection function, can in the mode of constant current stop voltage, battery be full of;
LED driving circuit (C4) drives diode displaying Product Status or imitation flame;
Module arranges five pins at least.Described the first pin is the output pin that light-emitting diode drives, and the second pin is the ground wire pin, and the 3rd pin is the switch input pin, and the 4th pin is power pins, and the 5th pin is output pin.
Charge mode testing circuit (C2) but detection module is in battery charging mode according to user or normal glow mode, module can be charged or driven heating work.When the voltage of the 4th pin (OUT) is higher than the voltage of the 5th pin (BAT), then integration module is in charge mode, through the 4th pin (OUT) from the USB power taking, to do the battery charging.When the voltage of the 5th pin (BAT) was higher than or is equal to the voltage of the 4th pin (OUT), then integration module was in normal febrile state, collect switch command from the 3rd pin (SW) again after, drive heating work.The setting of the 4th pin and the 5th pin can increase other pin and separately do charging and drive the electro-heat equipment of being located at module-external, can reduce the encapsulation expense and do module with some less encapsulation.
Battery charging and protective circuit (C3) provide outside lithium battery or the charging of other rechargeable battery and battery protection function, can in the mode of constant current stop voltage, the single-lithium-battery pond be full of.And it can see through USB interface and connect other electronic product, directly utilizes the USB power supply to charge.In operating state at ordinary times, it can detect the voltage of lithium battery group, and the protection battery is avoided over-discharge can.Lithium battery can be different capabilities, difformity and different encapsulation.Lithium battery power supply can be directly used like this, Li battery protection IC and charging chip need not be added in addition.
LED driving circuit (C4) drives the diode displaying Product Status or imitates the firework light that smells good after the switch command that receives the 3rd pin (SW).
As shown in Figure 2, described line with heating function circuit is given the electro-heat equipment of being located at module-external with PWM formal output voltage; Switch command from the 3rd pin (SW) through logic simulator (Emulator Logic) to the PWM controller.The line with heating function circuit comprises logic simulator (Emulator Logic), PWM controller (PWMControl), Bulk Switch.Comprise also in the module that low pressure detects (LVD), band-gap reference (BandgapReference), LED driving circuit (LED Driver), battery charging and protective circuit (BatteryCharger).
Application of the present invention as shown in Figure 3, integration module U of the present invention, electro-heat equipment HT, battery pack BT, switching device S, USB interface.Electro-heat equipment HT can be that heating wire, heating resistor or other utilize electric energy to produce the material of heat.Switching device S extracts or receives the heating signal.Integration module U of the present invention can connect different switching devices, comprises mechanical switch, such as touch-switch key and toggle switch key; Thermoswitch is such as thermistor; Photosensitive switch is such as photodiode; With the acoustic control air flow switch, such as various switching devices that are used for extracting or receiving the heating signal such as loudspeakers.
An Application Example of the present invention---electronic lighter, as shown in Figure 4, U2 is integration module of the present invention, BT2 is battery pack, and S2 is switching device, and HT2 is electro-heat equipment, CHG+ and CHG-are the positive and negative electrodes of USB interface, and D2 is light-emitting diode, and S1 is option switches.
After switching device S2 connected, to electro-heat equipment HT2, order was enough to burning-point cigarette to high temperature and the heat of electro-heat equipment HT2 generation to integration module U2 with the formal output voltage of PWM.At adstante febre, output current is to light-emitting diode D2 simultaneously for integration module U2, and light-emitting diode D2 luminescence display electro-heat equipment HT2 works.After S2 opened, integration module U2 can stop to drive electro-heat equipment HT2 and light-emitting diode D2 immediately.
If switching device S2 connects more than ten seconds continuously, integration module U2 can stop output voltage to electro-heat equipment HT2, and driving light-emitting diode D2 flashes to represent that fever time is long.
When lithium battery BT2 voltage is lower than 3.3 volts, after switching device S2 connects, integration module U2 can output voltage to electro-heat equipment HT2, and drive light-emitting diode D2 and flash to represent that cell voltage is too low.When lithium battery forces down in 3 volts, after switching device S2 connects, integration module U2 can output voltage to electro-heat equipment HT2 and light-emitting diode D2, avoid over-discharge can with the protection battery.
When the delivery outlet (OUT) of integration module U2 connected charge power supply through option switches S1, whole circuit entered charged state.Integration module U2 can be input to lithium battery BT2 to electric current (constant current 150mA) in the mode of constant current stop voltage, until battery is full of (pressure limiting 4.2V).When charging, integration module U2 can drive light-emitting diode D2 and produce high light, and the expression circuit is in charged state.When being full of electricity, integration module U2 can drive light-emitting diode D2 and produce low-light, and expression is full of electricity.
If cell voltage is more than 2.9V, integration module U2 is (150mA) charging at full speed, until battery is full of electricity.If cell voltage is below 2.9V, integration module U2 can charge with one of ten parts speed.This can protect battery and prevent from charging under short-circuit condition.
Fig. 5 is Another Application example of the present invention---the electrical schematic diagram of atomizer.U1 is monolithic semiconductor integration module of the present invention, and BT1 is battery pack, and MK1 is switching device (microphone), and HT1 is electro-heat equipment (heating wire), and CHG+ and CHG-are the positive and negative electrodes of USB interface, and D2 is the light-emitting diode of aobvious line status.The operation principle of this Application Example is basically the same with a upper Application Example, and the purposes that different places is electro-heat equipment connects the mode of USB interface when being connected.The electro-heat equipment of this application embodiment is the liquid as the traditional tobacco effect of atomizing simulation, then allows human body suck.When charging, need to take off first electro-heat equipment with family, then connect USB interface, to obtain power source charges.
