MM908E626AVDWB

Overview

The MM908E626AVDWB is an integrated single-package solution combining a high-performance HC08 microcontroller with a SMARTMOS analog control IC. It features four low RDS(ON) half-bridge outputs, an embedded LIN physical layer, and a switchable 5.0 V voltage regulator (HVDD). The device operates within a supply voltage range of 8.0 V to 18 V and supports junction temperatures from -40 °C to 135 °C. Key specifications include a typical half-bridge on-resistance of 425 mΩ at 25 °C and peak current capability of 5.0 A per half-bridge. It includes 16 KB of flash memory, 512 bytes of RAM, and a 10-bit ADC.

Feature Summary

• Integrated M68HC08EY16 core with 16 KB Flash and 512 B RAM
• Four half-bridge outputs with short-circuit and overtemperature protection
• Built-in LIN physical layer for automotive serial communication
• Switchable HVDD output for driving external sensors or loads

Applications

• Automotive climate control stepper motor drivers
• Light-leveling control systems
• DC motor and actuator control in industrial applications

Procurement Notes

Verify the specific suffix 'AVDWB' against official NXP documentation to confirm package type and temperature range. Ensure compatibility with the 54-pin SOICW-EP package requirements. Check for any specific ordering constraints or tape-and-reel options if applicable.

Selection Notes

Select this component for applications requiring integrated MCU, motor drive, and LIN communication in a single package. Ensure the load current does not exceed the 5.0 A peak rating per half-bridge. Verify that the operating voltage stays within the 8.0 V to 18 V nominal range for optimal performance.

Part Context

The MM908E626 belongs to the Freescale/NXP 908E series of integrated smart power devices. It is designed as a system-level solution for automotive body electronics, replacing discrete MCU, driver, and transceiver components to reduce PCB area and complexity.

Replacement Considerations

Check for direct pin-to-pin replacements such as other variants in the 908E family (e.g., MM908E622, MM908E624, MM908E625) depending on specific feature requirements like high-side switches or different I/O counts. Confirm software compatibility if migrating between similar MCU cores.
