MC33889BPEGR2

Specialized Overview

The MC33889BPEGR2 is a System Basis Chip (SBC) featuring a low-speed fault-tolerant CAN interface. It integrates a fully protected 5.0 V low-dropout regulator with 200 mA current capability, overtemperature detection, and reset functions. The device includes an external high-side power supply output (HS1) with 150 mA drive capability for wake-up inputs. It supports Normal, Standby, Stop, and Sleep modes to minimize standby current consumption. Communication is handled by a built-in low-speed 125 kbps CAN transceiver compatible with CAN 2.0 A and B protocols. Control and diagnostics are managed via a Serial Peripheral Interface (SPI).

Specialized Feature Summary

Specialized Procurement Notes

Verify the specific ordering suffix 'R2' indicates tape and reel packaging configuration. Confirm the 'B' variant designation against design requirements, as it differs from the 'D' version in CAN receiver thresholds and loop times. Ensure the SOICW package dimensions align with PCB layout constraints. Check for End of Life status updates prior to finalizing procurement plans.

Specialized Selection Notes

Select the MC33889BPEGR2 when designing systems requiring a monolithic solution for power management and module-to-module communication. This component is suitable for MCU-based applications needing integrated protection, diagnostics, and control. Consider the 'B' variant specifications if specific CAN threshold characteristics differ from the 'D' version. Evaluate thermal resistance and junction temperature limits during system integration.
