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. The 33889 has Normal, Standby, Stop and Sleep modes; an internally switched high-side power supply output with two wake-up inputs; programmable timeout or window watchdog, Interrupt, Reset, serial peripheral interface (SPI) input control, and a low-speed fault tolerant CAN transceiver, compatible with CAN 2.0 A and B protocols for module-tomodule communications. The combination is an economical solution for power management, high-speed communication, and control in MCU-based systems. This device is powered by SMARTMOS technology.
