NXP Semiconductors Technical Data System basis chip (SBC) with low speed fault tolerant CAN interface Document Number: MC33889 Rev. 15.0, 8/2016 33889 The 33889 is an SBC having a fully protected, fixed 5.0 V low drop-out regulator, with current limit, overtemperature prewarning and reset. An SBC device is a monolithic IC combining many functions repeatedly found in standard microcontroller-based systems, e.g., protection, diagnostics, communication, power, etc. An output drive with sense input is also provided to implement a second 5.0 V regulator using an external PNP.
