This is a electromagnetic compliance (EMC) vetted 3-stage power tree with controller area network (CAN) reference design that can be used in many automotive applications requiring operation with input voltages as low as 3.5 V.A system basis chip (SBC) is an integrated circuit (IC) that combines many typical building blocks of a system: which includes transceivers: linear regulators: and switching regulators. While these integrated devices can offer size and cost savings in a number of applications: the integrated devices do not work in every case. For applications where an SBC is not a good fit: it might be beneficial to build a discrete implementation of these aforementioned building blocks thus making a discrete SBC.
