MC33889DPEG

System Basis Chip, CAN, 2x 5V/200mA LDOs, SOIC 28

Overview

The ® MC33889 is a monolithic IC combining functions frequently used in MCU-based systems, making it an economical solution for providing power, low speed fault tolerant communication, and control.

* 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

* Provides the drive and sense inputs necessary to implement a second 5.0 V regulator using an external series pass PNP that is resistor ratio adjustable to meet peripheral needs

* Support both single-coil and multi-coil A type applications

* Economical solution for providing power, low speed fault tolerant communication, and control needed for MCU based systems.
