MC33989: System Basis Chip with High Speed CAN

Overview

The NXP^® MC33989 is a monolithic integrated circuit that combines many functions frequently used in MCU-based systems, making it an economical solution for providing power, high speed communication, and control.

Fully protected fixed 5.0 V low drop regulator output with current limit, over temperature pre-warning, and reset provides power for CAN and the MCU
Provides drive and sense inputs to implement a second 5.0 V regulator using an external series pass PNP that is resistor ratio adjustable to meet peripheral needs
An internally power supply voltage output with four wake-up inputs, programmable window watch-dog, interrupt, reset, high speed CAN transceiver and SPI input control
