Power Management and System Basis ICs


Image

ST provides a large selection of Power Management and System Basis Chips (SBC) specifically conceived to fit into Electronic Control Units (ECU) for infotainment, body control and door zone modules applications.

Combining several power management building blocks, like linear and switching voltage regulators and high side switches, with an extensive set of diagnostic and protection features, including short circuit and overvoltage, together with I2C control bus and physical LIN and CAN transceivers, they are ideal companions to a microcontroller.

Manufactured with ST’s mixed signal power technologies, they meet and exceed quality and reliability requirements for vehicle on-board electronics.
