The 33903/4/5 is the second generation family of the System Basis Chip (SBC). It combines several features and enhances present module designs. The device works as an advanced power management unit for the MCU with additional integrated circuits such as sensors and CAN transceivers. It has a built-in enhanced high-speed CAN interface (ISO11898-2 and -5) with local and bus failure diagnostics, protection, and fail-safe operation modes. The SBC may include zero, one or two LIN 2.1 interfaces with LIN output pin switches. It includes up to four wake-up input pins that can also be configured as output drivers for flexibility. This device is powered by SMARTMOS technology.
This device implements multiple Low-power (LP) modes, with very low-current consumption. In addition, the device is part of a family concept where pin compatibility adds versatility to module design.
