MM908E625ACPEKR2

Overview

The MM908E625ACPEKR2 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 and one low RDS(ON) high-side output, designed for automotive mirror, door lock, and light-leveling applications. The device includes a LIN physical layer, autonomous watchdog with cyclic wake-up, and a switchable internal VDD output. Operating within a temperature range of -40°C to 85°C, it utilizes a 54-pin SOICW-EP package.

Feature Summary

• Integrated M68HC908EY16 core with 16 KB flash and 512 B RAM
• Four half-bridge outputs (RDS(ON) typ 425 mΩ) and one high-side output (RDS(ON) typ 600 mΩ)
• Built-in LIN physical layer for single-wire communication
• Autonomous watchdog with cyclic wake-up capability

Applications

• Automotive mirror control systems
• Door lock actuators
• Light leveling applications

Procurement Notes

Verify the 'R2' suffix indicates tape and reel packaging as specified in the datasheet ordering information. Confirm the 'EK' suffix corresponds to the standard tube packaging variant if bulk quantities are required instead of reels. Ensure the component meets AEC-Q100 qualification standards for automotive use.

Selection Notes

Select this part for applications requiring integrated motor control and MCU functionality in a compact form factor. Ensure the supply voltage remains between 8.0 V and 18 V. Verify that the thermal requirements for the 54-SOICW-EP package are met, particularly given the power dissipation from the half-bridge drivers.

Part Context

This component belongs to the MM908E625 series, which integrates SMARTMOS technology with HC08 MCUs. It is designed to replace discrete solutions by combining power switches, diagnostics, and control logic into a single chip, reducing PCB space and system complexity for automotive body electronics.

Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as MM908E624 or MM908E626 variants, ensuring memory size and I/O configurations match the application requirements.
