NXP® has more than 20 years of experience in the development of sophisticated power management integrated circuits (PMICs). In the realm of linear voltage regulation, NXP has developed a family of PMIC products that combine several popular functions that are typically used in automotive MCU-based systems. These device types are referred to as System Basis Chips (SBCs). They utilize Our SMARTMOS® technology.
The devices contain a combination of Low Drop Out (LDO) voltage regulator(s), High side switches and many have a physical layer transceiver (CAN, LIN). The SBC devices are controlled by an MCU through a SPI interface. They also possess various power saving modes such as standby, sleep and stop, along with other features such as wakeup, watchdog timer, etc..
