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 integrated following circuit of module: heating line circuit, charge mode testing circuit, battery charge and protective circuit, LED driving circuit;
Heating line 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 charge and protective circuit (C3) provide lithium battery or rechargeable battery charging and battery protection function, can battery be full of in the mode of constant current stop voltage;
LED driving circuit (C4) driven for emitting lights diode shows Product Status or imitation flame;
Module is provided with five pins at least.Described first pin is the output pin that light-emitting diode drives, and second pin is the ground wire pin, and the 3rd pin is the switch input pin, and the 4th pin is a power pins, and the 5th pin is an 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) was higher than the voltage of the 5th pin (BAT), then integration module was in charge mode, through the 4th pin (OUT) from the USB power taking, to make the usefulness of battery charge.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 littler encapsulation.
Battery charge and protective circuit (C3) provide outside lithium battery or charging of other rechargeable battery and battery protection function, can the single-unit lithium battery be full of in the mode of constant current stop voltage.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-ion cell protection chip and charging chip need not be added in addition.
LED driving circuit (C4) is after the switch command that receives the 3rd pin (SW), and the driven for emitting lights diode shows Product Status or imitates the pyrotechnics light that smells good.
As shown in Figure 2, described heating line circuit is given the electro-heat equipment of being located at module-external with PWM form output voltage; Switch command from the 3rd pin (SW) through logic simulator (Emulator Logic) to the PWM controller.The heating line 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 charge 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, as touch-switch key and toggle switch key; Thermoswitch is as thermistor; Photosensitive switch is as photodiode; With the acoustic control air flow switch, 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 an integration module of the present invention, BT2 is a battery pack, and S2 is a switching device, and HT2 is an electro-heat equipment, CHG+ and CHG-are the positive and negative electrodes of USB interface, and D2 is a light-emitting diode, and S1 is an option switches.
After switching device S2 connected, integration module U2 gave electro-heat equipment HT2 with the form output voltage of PWM, and the high temperature and the heat that make electro-heat equipment HT2 produce are enough to burning-point cigarette.At adstante febre, integration module U2 output current simultaneously gives light-emitting diode D2, and the luminous demonstration electro-heat equipment of light-emitting diode D2 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 and give electro-heat equipment HT2, and driven for emitting lights diode D2 flashes with the expression fever time long.
When lithium battery BT2 voltage was lower than 3.3 volts, after switching device S2 connected, integration module U2 can not give electro-heat equipment HT2 by output voltage, and driven for emitting lights diode D2 flashes with the expression cell voltage too low.When lithium battery forced down in 3 volts, after switching device S2 connected, integration module U2 can not give electro-heat equipment HT2 and light-emitting diode D2 by output voltage, avoids over-discharge can with the protection battery.
When the delivery outlet (OUT) of integration module U2 connected charge power supply through option switches S1, entire circuit entered charged state.Integration module U2 can be in the mode of constant current stop voltage, and (constant current 150mA) is input to lithium battery BT2 electric current, is full of (pressure limiting 4.2V) up to battery.When charging, integration module U2 can produce high light by driven for emitting lights diode D2, and the expression circuit is in charged state.When being full of electricity, integration module U2 can produce low-light by driven for emitting lights diode D2, and expression is full of.
If cell voltage is more than 2.9V, integration module U2 is (150mA) charging at full speed, is full of up to battery.If cell voltage is below 2.9V, integration module U2 can charge with one of ten parts speed.This can protect battery and prevent to charge under short-circuit condition.
Fig. 5 is Another Application example of the present invention---the electrical schematic diagram of atomizer.U1 is a monolithic semiconductor integration module of the present invention, and BT1 is a 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 that is used for showing line status.The operation principle of this Application Example is the same with a last Application Example basically, and the purposes that different places is electro-heat equipment is connected the mode of USB interface during with charging.Should be liquid with the electro-heat equipment of embodiment, allow human body suck then as the traditional tobacco effect of atomizing simulation.When charging, need take off electro-heat equipment earlier with family, connect USB interface then, to obtain power source charges.
