Integrated circuits (ICs) are essential to vehicle control units. System ICs ensure actuator movements, information handling and safety relevant actions.
Restraint system ICs contain all peripheral system functions: Interfaces to connect crash sensors to the electronic control unit, firing loop drivers for airbag deployment, extensive safety and diagnosis mechanisms to constantly monitor the system integrity. They also provide power for the entire system.
Powerful microelectronics for assisted and automated driving. The new radar SoCs use advanced 22 nm RF-CMOS technology to ensure reliable obstacle recognition with integrated data processing.
Bosch’s park pilot system simplifies parking with precise ultrasonic sensing. The ultrasonic sensor IC delivers real-time object detection and reliable distance measurement for safer, smarter maneuvers.
The automotive IC portfolio contains power supply ICs for electrical and combustion engine powertrain management for virtually all current microcontrollers and peripheral sensors, as well as malfunction monitoring ICs, which step in to control the power supply and protect the powertrain. Oxygen sensor interface ICs, power stage ICs, alternator regulators, and an efficient one-chip solution for driving 3-phase BLDC motors complete the portfolio.
Integrated circuits are essential parts of electric vehicle powertrain systems. The programmable gate driver allows to adapt the gate charge and discharge profiles of up to four power transistors to the actual inverter operating condition during runtime.
CAN networks continue to be popular due to their robustness, cost efficiency, simplicity and flexibility in terms of network topologies.
Bosch’s CAN SIC XL Transceiver allows the operation of CAN XL networks at maximum speed of up to 20 Mbit/s.
Automotive ICs are essential to a vehicle’s control units. These custom chips ensure actuator movements, information handling, and take over safety-relevant actions. They open up possibilities for customer-specific adaptations and are important levers for reducing manufacturing costs. Bosch develops and manufactures integrated circuits for safety-critical applications up to the highest ASIL (Automotive Safety Integrity Level) D.
How automotive ICs from Bosch shape modern driving experiences
Bosch has long-standing experience in the many steps that come with the development and production of automotive ICs: architecture, partitioning, calculation using state-of-the-art methods, verification, validation and testing, process definition, and packaging. We manufacture integrated circuits since 1970 and have successfully brought more than 450 smart power, digital, and high-frequency circuits into series production.
Bosch offers integrated circuits for various applications:
Our portfolio of custom chips takes the needs of developers and manufacturers of electronic system components (Tier 1, EMS, OEM) into account. It includes classic control units as well as sensors, transmitters, receivers, and special controls for actuators.
What are the key functions of custom chips in vehicles?
Automotive ICs from Bosch are often located at the interface between microcontrollers and peripherals. They provide the required operating voltages, capture sensor data, monitor the correct functioning of other components, make logical decisions, communicate with the microcontroller, and control actuators.
Custom chips from Bosch are manufactured in the company’s own semiconductor fabs in Reutlingen and Dresden as well as by technology partners. Bosch relies on early cooperation with customers in the application and integration into their integrated circuits, modules, power electronics, and sensors.
