When described button closure is not during super scheduled duration, the second power electronic device conduction level is exported in the control output end of described Based Intelligent Control device; When described button is closed, surpass after scheduled duration, the second power electronic device break opening contact is exported in the control output end of described Based Intelligent Control device.
During work, when pushing button, discharge capacity electric discharge, makes the first power electronic device conducting, thereby battery unit is started, can be to the power supply of power supply object.Conventionally after starting, initialize program sets high the control output end of Based Intelligent Control device, keeps the power supply state after pulse enable; Its sampled signal input is controlled the closed overtime or brownout of button as monitored; automatic control output end is set low; thereby by the second power electronic device, control the first power electronic device and close power supply; avoid the abnormal improper electric discharge of the closed power brick causing of button; effectively prevent meaningless power consumption, and protect power brick and power supply object thereof.
Of the present utility model improving is that another road of controlled end of described the second power electronic device (Q2) connects wakes start-up circuit up.
Further, described in wake start-up circuit up and formed by charge initiation circuit, described charge initiation circuit consists of the charging socket circuit containing charging socket (J1).
Further, described in wake start-up circuit up and formed by communication start-up circuit, described communication start-up circuit consists of the communication socket circuit containing connecing the communication plug receptacle (J2) of power supply object control circuit communication terminal.
Further, described in, waking start-up circuit up consists of charge initiation circuit in parallel and communication start-up circuit; Described charge initiation circuit consists of the charging socket circuit containing charging socket (J1); Described communication start-up circuit consists of the communication socket circuit containing connecing the communication plug receptacle (J2) of power supply object control circuit communication terminal.
Make like this utility model except button starts, there is the charging socket of insertion, accept the multiple Starting mode such as communication instruction.
Further again, between the controlled end of described power electronic device and control button (SW1), be also connected to voltage-stabiliser tube (D3).When this voltage-stabiliser tube can prevent that cell voltage is too low, cannot start-up circuit, to avoid frequent starting to damage battery.
The utility model is simple and reasonable, has properly settled the abnormal closed problem that causes battery to be crossed putting of prior art ubiquitous control button, and power brick and power supply object thereof are played to effective protective effect.
