A kind of electronic igniting controllor; Comprise magnetic induction fire signal interface, Drive and Control Circuit, power tube, power interface and protective circuit; It is characterized in that: also comprise angle of attachment control and angle of attachment logic control; Fire signal is input to the angle of attachment logic control through closure control, exports through Drive and Control Circuit again.
The utility model is applicable to the magnetic induction type energy electronic ignition system for high, and has protective functions such as perfect overcurrent, overvoltage, the reversal connection of mistake zero-sum accumulator polarity, is applicable to the energy electronic ignition system for high that the magnetic induction type fire signal triggers.Multiple magnetic induction type signal generator for ignition is complementary; Its working power voltage wider range can be applicable to the Automotive Electronic Ignition System under the rugged environment.
Embodiment
The angle of attachment control circuit adopts " variable threshold value " design, and when the slow-speed of revolution, conduction threshold is generally got 250mV, and when high rotating speed, this threshold value then becomes negative value, and this makes angle of attachment to shift to an earlier date about 5%.
The primary current of overcurrent restriction point fire coil selects resistance to detect with the electric current on the power tube emitter; The threshold value of over-current limit circuit is got 260mV; When the electric current that flows through on the current sampling resistor surpasses predetermined value; Current limit circuit just reduces the driving current of power tube base stage, thereby prevents that electric current on the spark coil is excessive and cause unnecessary loss.
Overvoltage Limiting is the collector electrode over-voltage breakdown that prevents power tube Q, specialized designs the overvoltage threshold circuit, can confirm the threshold value of overvoltage through external divider resistance.
When the stall power-off protection was cut off the power supply when load, the disconnected protective circuit of the stall of IC interior was turn-offed external power tube at once, and its threshold value can be adjusted through branch pressure voltage.
