MC33389CDW Description

Short technical summary and product information.

The MC33389CDW from NXP Semiconductors is a monolithic integrated circuit designed for automotive Engine Control Units (ECUs). It features a low-speed, 125 kBaud fault-tolerant CAN transceiver, compatible with the 33388 physical interface.

 

This device incorporates dual low-drop voltage regulators with 100 mA and 200 mA current capabilities, including current limitation and over-temperature detection. The V1 regulator provides a 5.0 V output. It supports three operational modes: Normal, Stand-by, and Sleep.

 

Additional features include three external high-voltage wake-up inputs, a V3 VBAT switch with 100 mA output current capability for driving external switches or relays, and VBAT monitoring with failure detection. The operating voltage ranges from 5.5 V to 18 V, with a maximum transient voltage of 40 V. The MC33389CDW is supplied in a 28-SOIC package suitable for surface mounting.

 

It offers programmable software window watchdog and reset functions, along with wake-up capabilities via CAN interface or local programmable cycle wake. Communication with the MCU is handled through an SPI interface.
