MCZ33905DD5EKR2

System Basis Chip, 2 LIN, 2x 5V/400mA LDOs, 3/4 wakeup, SOIC-EP 54

Overview

The ® MC33905 is part of a second generation family of system basis chips, combining multiple features and enhanced module design.

* The MC33905 works as an advanced power management unit for the MCU and additional integrated circuits such as sensors and CAN transceivers

* Built-in enhanced high-speed CAN interface ISO11898-2 and -5, with local and bus failure diagnostics, protection and fail-safe operation mode.

* The SBC may include zero, one or two LIN 2.1 interfaces with LIN output pin switches

* Includes 2 or 3 wake-up input pins than can also be configured as output drivers for flexibility

## Features

* Voltage regulator for MCU, 5.0 V or 3.3 V, part number selectable, with possibilty of usage external PNP to extend current capability and share power dissipation

* Voltage, current and temperature protection

* Extremely low quiescent current in low-power modes

* Fully-protected embedded 5.0 V regulator for the CAN driver

* Multiple under-voltage detections to address various MCU specifications and system operation modes i.e. cranking

* Auxiliary 5.0 V or 3.3 V SPI configurable regulator, for additional ICs, with over-current detection and under-voltage protection

* MUX output pin for device internal analog signal monitoring and power supply monitoring

* Advanced SPI, MCU, ECU power supply and critical pins diagnostics and monitoring.

* Multiple wake-up sources in low-power modes: CAN or LIN bus, I/O transition, automatic timer, SPI message and VDD over-current detection.

* ISO11898-5 high-speed CAN interface compatibility for baud rates of 40 kb/s to 1.0 Mb/s

* This product is included in NXP’s  product longevity program with assured supply for a minimum of 15 years after launch
