MCZ33897BEFR2

Drivers, Receivers, Transceivers Overview

The MCZ33897BEFR2 is a Single Wire CAN (SWCAN) transceiver manufactured by NXP Semiconductors, formerly Freescale. It provides the physical layer for digital communications over a single-wire medium using CSMA/CR protocols. The device operates directly from a vehicle's 12 V battery system or broad DC-power sources within a supply voltage range of 5.0 V to 40 V. It supports two data rates: low speed at 33.33 kbps and high speed at 83.33 kbps. Key electrical characteristics include a worst-case sleep mode current of 60 µA, undervoltage lockout starting at 4.0 V, and thermal shutdown protection at 150 °C. The component is housed in an 8-terminal SOICN package with an operating temperature range of -40 °C to +125 °C.

Drivers, Receivers, Transceivers Feature Summary

• Waveshaping capability designed to minimize electromagnetic interference (EMI).
• High-voltage wake-up feature allows control of external regulators and reactivation of the system.
• Automatic detection and handling of loss of ground conditions via the LOAD switch.
• Built-in current limit and thermal shutdown protect against bus shorts and overheating.

Drivers, Receivers, Transceivers Applications

• Single Wire Controller Area Network (SWCAN) physical layer implementation.
• Factory or assembly line communications utilizing high-speed data rates.
• System communications requiring low radiated EMI at standard speeds.
• Automotive modules requiring energy-efficient sleep modes controlled by the transceiver.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix EF indicates Pb-free packaging as documented. Confirm the device variant corresponds to the 8-terminal package configuration. Ensure compatibility with the intended application diagram for devices lacking the CNTL terminal. Check for any updates regarding the GMW3089v2.4 specification compliance during sourcing.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when board space is limited due to its 8-pin package form factor. Choose this model if the application does not require the module regulator to be controlled via a dedicated control terminal. Ensure the design accommodates the absence of the CNTL pin present in other series variants. Verify that the lack of internal reverse battery protection aligns with the external circuitry plan.

Drivers, Receivers, Transceivers Part Context

This component belongs to the 33897 Series, which includes variations such as the 33897A, C, D, and T. The 'B' designation specifically identifies the 8-terminal package version without the CNTL terminal. The 'EF' suffix denotes lead-free packaging compliant with RoHS standards. The series is designed to comply with General Motors Corporation specification GMW3089v2.4.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include MC33897CTEF. Verify parameter equivalence before substitution. Other series members like MC33897DEF share similar features but differ in package or terminal configurations.
