Power Management ICs for Automotive Body Control

Power Management ICs for Automotive Body Control

ROHM's power management ICs, designed for automotive body applications, integrate regulators that supply voltage to microcontrollers in equipment such as ITS (Intelligent Transport System), body control, and AV, watchdog timer voltage detector ICs that monitor the microcontroller, power supplies for hybrid systems, and LED drivers. All models feature high reliability and low power consumption for longer battery life
