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.
