Infineon low-end airbag system design
Safety electronics is one of the important driving factors for reducing the number of deaths and injuries in road traffic accidents. Today, not only consumers need it, the government is also passing legislation to achieve this goal.
In areas such as electronic power steering, safety can be combined with reducing fuel consumption / emissions reduction and improving the overall energy efficiency of the car.
Infineon is one of the few broadband suppliers. Its products include smart sensors, 8, 16, and 32-bit microcontrollers, automotive power standard products, special standard products (ASSP), and highly integrated customized special ICs ( ASIC). This flexibility and our system expertise, as well as 40 years of experience in the automotive industry, enable us to support our customers by solving the major challenges they face.
These challenges include cost optimization, strict quality requirements, and solving future challenges in the security market, such as meeting future safety integrity level requirements.
Advantages of low-grade airbag systems
With the help of chipsets for basic airbag systems, we can support low-cost designs for emerging markets
16 / 32-bit microcontrollers can provide the performance of 32-bit products at the price of 16-bit products
Dedicated mixed-signal airbag ASSP can provide high flexibility and upgradeability for up to 10 ignition circuits

Permanent magnet Dc Motor is composed of stator magnetic pole, rotor, brush, case and so on. Stator magnetic pole is made of permanent magnet (permanent magnet steel), ferrite, alnico, ndfeb and other materials, and the rotor is generally made of silicon steel laminated. Enameled wire is wound between two slots in the rotor core (three slots are provided with three windings), and its joints are separately welded on the metal sheet of the commutator. Electric brush is a conductive part connecting power supply and rotor winding. Permanent magnet motor brush USES single metal sheet or metallic graphite brush, electrochemical graphite brush.Permanent Magnet Gear Motor is established using permanent magnet magnetic field of a dc motor. Permanent magnet Gear Motor is widely used in various kinds of portable electronic equipment or apparatus
precision instruments and meters,automobile industry, medical equipment, consumer electronics, household appliances, electric glass doors and Windows,etc., wide application range,,Permanent Magnet Gear Motor is usually used in small power occasion.
Features: permanent
magnet gear motor is a kind of rectangular pulse wave, sine wave current, in the form of hybrid permanent magnet motor. Simple structure, high reliability and high efficiency.
Method of use: the best stable in horizontal plane, installed on the permanent magnet gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the permanent magnet gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
permanent magnet gear motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
permanent magnet gear motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of permanent magnet gear motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
