Embodiment Construction

[0024] Core idea of ​​the present invention:

[0025] (1) Realize the communication protocol of ignition drive bus IDBUS;

[0026] (2) Support non-polar two-wire bus, power supply and communication;

[0027] (3) The charging voltage is configurable and can be directly ignited by external control;

[0028] (4) Support chip information injection, including chip UID code, ignition password, clock calibration value, default delay value, etc. The ignition password can only be read by the chip and compared inside the chip, and does not support any other way to read out the chip ;

[0029] (5) Support various safety measures such as emergency discharge, safe discharge, switch and voltage state detection, charge and discharge circuit detection;

[0030] (6) Chip low power consumption design, ignition and discharge circuit supports instantaneous high current and high voltage;

[0031] (7) Formulate standard ignition preparation and operation procedures;

[0032] (8) Ignition devic...

Abstract

The invention relates to an ignition driving chip and a control method. The chip supports a communication protocol of an ignition driving bus IDBUS; a nonpolar dual-wire bus is used for communicationand electrification; a pulse width modulating mode is used for communication; a lower standard pulse width value can be configured as needed; an upper standard pulse width value is fixed; a chip structure comprises all function modules for processing communication instruction sets and finishing ignition operations; a charging voltage value can be externally configured; and the ignition initiationcan be instructed or directly controlled by external signals. The chip control method consists of ignition device information injection, ignition device ignition preparation and ignition device ignition operation. Through the mode, such functions of system networking ignition, single device ignition and instruction or direct ignition can be achieved; the control flow is specified; the applicationscene is widened; the ignition digital controllability is realized; and the chip achieves high communication interference resistance, reliability, usability, configurability and high safety, and can assist the digital upgrading of associated ignition industries.

Description

technical field [0001] The invention relates to the technical field of electronic ignition drive, in particular to an ignition drive chip and a control method.
