SBC SolutionsFreescale Semiconductor has years of experience developing

sophisticated power management integrated circuits. In the realm

of linear and switched mode power supply (SMPS) voltage

regulation, Freescale has developed a family of products that

combine several popular functions typically used in MCU-based

automotive systems. Called System Basis Chips (SBCs), these

devices are designed to provide advanced power management

and functional safety for the MCU along with additional integrated

circuits such as sensors and CAN and LIN transceivers.

System Basis Chips combine low drop out (LDO) voltage regulators,

switching voltage regulators, with physical layer transceivers

(CAN, LIN), which are the primary functions of the IC. More than

a stand alone power management IC, these system oriented

solutions help your design in terms of safety, analog and digital

flexibility, family device scalability, robustness and finally system

cost savings.

Controlled by an MCU through a serial peripheral interface (SPI),

SBCs provide power saving modes and functional safety. SBCs

are the ideal companion for MCUs to make your embedded

system safely powered for automotive and industrial markets.
