MC33389 : System Base Chip
The MC33389 is a monolithic integrated circuit combining
functions frequently used in microcontroller based systems. The
MC33389 includes two internal low drop 5.0 V regulators with current
limit, over temperature pre-warning, and reset to provide power for
CAN and the MCU plus other peripherals. MC33389 has normal, standby,
and sleep modes, an internally switched high-side power supply
voltage output with three wake-up inputs, programmable window
Watch-Dog, Interrupt, Reset, fault tolerant low speed CAN
transceiver for module-to-module communication, and SPI input
control. The combination is an economical solution for providing
power, low speed fault tolerant communication, and control needed
for MCU based systems. .
MC33389 Features
Two 5.0 V low-drop voltage regulators, with respective 100 mA
and 200 mA current capabilities, current limiting, and over
temperature pre-warning
Normal, standby, and sleep modes separate from CAN interface
modes
Low speed 125 kB/s fault tolerant CAN interface, compatible with
MC33388 stand-alone physical interface
