Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33742 Rev 2.0, 10/2004 Advance Information System Basis Chip (SBC) with Enhanced High-Speed CAN Transceiver The 33742 and the 33742S are monolithic integrated circuits combining many functions frequently used by automotive environmental control units (ECUs). The 33742 is an SBC having a fully protected fixed 5.0 V low-drop regulator with current limit, overtemperature pre-warning, and reset. An output drive with sense input is also provided to implement a second 5.0 V regulator, using an external PNP bipolar junction transistor.
