Electric brake boosters aim to reduce the amount of pedal pressure needed for braking. They use a sensor in the brake pedal to read driver's actions and are progressively replacing mechanical vacuum brake booster systems.
Increasingly used by car makers to enhance driver comfort and passenger safety, electric brake boosters use a dedicated electronic system to process the signals from the brake pedal and operate the master cylinder by means of a brushless DC (BLDC) motor.
To simplify the design of these solutions, ST has a full range of 3-phase gate drivers and Power MOSFETs for driving BLDC motors, including for 48 V domains. We can provide SPC5 32-bit automotive microcontrollers, dedicated power management ICs, and CAN transceivers as well as a wide range of flexible and innovative application-specific standard products (ASSP), covering any possible system partitioning.
