MC33989 : System Base Chip with High Speed CAN
The MC33989 is a monolithic integrated circuit combining many
functions frequently used in microcontroller based systems. A 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. The MC33989 also provides the drive and sense inputs
necessary to implement a second 5.0 V regulator, sing an external
series pass PNP, that is resistor ratio adjustable to meet
peripheral needs. MC33989 has normal, standby, stop, nd sleep modes,
an internally switched high-side power supply voltage output with
four wake-up inputs, programmable window Watch-Dog, Interrupt,
Reset, high speed CAN transceiver for module-to-module
communication, and SPI input control. The combination is an
economical solution for providing power, high speed communication,
and control needed for MCU based systems.
