The first special chip for ignition drive of automobile electronic airbag in China was successfully developed by National Core Technology.

Thanks to CTOnews.com netizens for the delivery of clues on the way! CTOnews.com June 5 news, Suzhou National Core Technology Co., Ltd. issued a notice that the first generation of automotive electronic airbag ignition drive special chip product "CCL1600B" recently successfully tested in the company, marking the success of China's first automotive electronic airbag ignition drive special chip research and development.

Guoxin Technology's first automotive airbag electronic ignition chip CCL1600B is a mixed signal system integrated IC for airbag applications. The CCL1600B chip integrates power module, trigger circuit module, sensor interface module and complex security module into a single chip, which officials say can replace foreign products such as the Bosch CG90X series and ST's L9679 series. The highly compact dual-chip airbag ACU (airbag controller) composed of the mixed-signal system IC and CNIC's gauge-level microcontroller chip will realize the national production scheme of automobile airbag.

The CCL1600B chip is based on the first generation airbag ignition drive chip developed by the high voltage mixed signal platform. The package form is TQFP128epad, and the model is divided into CCL1600B1L4 (without CAN function) and CCL1600B2L4 (with CAN function).

The chip provides up to 16 airbag ignition circuits, 6 PSI5 sensor interfaces, 10 resistance or Hall element detection paths, and 2 high voltage PWM output interfaces with enhanced safety detection and automatic diagnosis functions; the configuration of the power supply system can solve the power supply problem of other chips in the ECU (electronic control unit) and integrates one CAN physical interface (supported by the CCL1600B2L4 model).

CTOnews.com Note: the airbag system is mainly divided into four parts: sensor, airbag computer, gas generator and airbag. When the collision occurs, the collision sensor transmits the signal to the airbag computer through the CAN bus, and the computer sends the ignition signal after judgment, which makes the airbag expand and pop up instantly. Electronic ignition chip, a key part of airbag, has become an important part of automotive electronic chip jam in China because of its technical difficulty, high development cost and technical blockade.
