Engine management systems

Bosch system ICs for engine management systems combine the power supply with additional peripheral functions. Virtually all current microcontrollers are supported.
The portfolio also covers a wide range of ICs for dedicated system functions such as power supply, sensor interfaces, oxygen sensor control, drivers for direct injection, ignition and other loads or actuators.
