MM908E624ACPEWR2

Overview

The MM908E624ACPEWR2 is an integrated single-package solution combining a high-performance HC08 microcontroller with a SmartMOS analog control IC. It features three low RDS(ON) high-side outputs, a LIN physical layer interface, and a current sense operational amplifier. The device includes a 16 KB flash memory, 512 bytes of RAM, a 10-bit ADC, and two 16-bit timers. Designed for automotive applications, it operates within a supply voltage range of 5.5 V to 18 V and supports ambient temperatures from -40°C to 85°C.

Feature Summary

• Integrated M68HC908EY16 core with 16 KB Flash and 512 B RAM
• Three high-side switches (HS1, HS2, HS3) with diagnostic functions
• Built-in LIN physical layer for serial communication
• Current sense operational amplifier with rail-to-rail input

Applications

• Automotive window lift systems
• Sunroof relay drivers
• Fan motor control

Procurement Notes

Verify the AC suffix indicates the -40°C to 85°C operating temperature range and the PEW suffix denotes the 54-pin SOICW package. Confirm the R2 suffix corresponds to tape and reel packaging as specified in the ordering information. Check component status as this series may be discontinued.

Selection Notes

Select the MM908E624ACPEW variant for standard automotive temperature ranges (-40°C to 85°C). Choose the AYPEW variant if operation up to 125°C is required. Ensure the application utilizes a 54-pin SOICW footprint and requires a single-wire LIN interface with integrated high-side switching capabilities.

Part Context

This component belongs to the MM908E62x family of integrated MCU and driver solutions. It shares the same core architecture with variants like the MM908E622 and MM908E626 but differs in output configuration, specifically offering three high-side switches instead of H-bridges or quad half-bridges.

Replacement Considerations
