NXP Semiconductors MM908E624AYPEWR2

Overview

MM908E624AYPEWR2 from NXP Semiconductors (formerly Freescale) is an integrated automotive-grade triple high-side switch with embedded HC08 MCU and LIN physical layer, designed for relay-driven motor control. It delivers 16 KB flash, 512 B RAM, 10-bit ADC, three diagnostic-capable high-side outputs (HS1–HS3), and a 5.0 V LDO regulator - all in a single 54-pin SOICW package rated for -40°C to +125°C operation. It targets window lift, sunroof, and fan control in body electronics.

For engineers reviewing the MM908E624AYPEWR2 datasheet, MM908E624AYPEWR2 pinout, MM908E624AYPEWR2 application, or MM908E624AYPEWR2 equivalent, this page provides verified functional identity, validated pin roles, confirmed thermal and electrical specs, LIN timing behavior, and real-world automotive use context - no generic claims or inferred capabilities.

Technical Context

The MM908E624AYPEWR2 integrates two die: an HC08-based MCU die (M68HC908EY16 core, 8 MHz bus, SPI/ESCI/ADC) and an analog SmartMOS die providing power switching, LIN transceivers, voltage regulation, and diagnostics. The MCU controls HS1–HS3 via SPI commands with sub-10 μs activation delay, while the analog die handles overcurrent, overtemperature, and wake-up detection independently.

LIN communication operates at up to 20 kbps with programmable slew rate (normal/slow/fast), and supports recessive/dominant state timing per ISO 17987. Wake-up inputs L1/L2 trigger system exit from Stop/Sleep modes within ≤80 μs, and the current-sense op-amp (±25 mV offset, 1 MHz GBW) enables inline load monitoring without external components.

FAQ

What is the maximum operating junction temperature for MM908E624AYPEWR2?

The MM908E624AYPEWR2 has a guaranteed operating junction temperature range of -40°C to +125°C. Its analog die thermal shutdown activates at 155–190°C (HS1/HS2/HS3), and over-temperature prewarning triggers at 120–160°C - both reported via SPI status registers. This ensures safe operation in under-hood environments when mounted with adequate copper pour.

Does MM908E624AYPEWR2 support direct PWM control of its high-side outputs?

Yes, MM908E624AYPEWR2 supports direct PWM control of HS1 and HS2 via the PWMIN pin, enabling fast-response relay actuation without MCU intervention. HS3 is controlled exclusively through SPI commands. The PWMIN input accepts logic-level signals (0–5 V) with 1.5 V typical threshold and supports frequencies up to 20 kHz based on propagation delays and slew-rate settings.

How does the current sense operational amplifier in MM908E624AYPEWR2 function?

The MM908E624AYPEWR2 includes a dedicated rail-to-rail input op-amp with +E and -E differential inputs and OUT single-ended output. It features ±25 mV input offset, 1 MHz gain-bandwidth, and 0.5 V/μs slew rate - enabling accurate bidirectional current measurement across shunt resistors. Output voltage scales linearly with sensed current and is readable via MCU ADC.

Can MM908E624AYPEWR2 operate without an external crystal?

Yes, MM908E624AYPEWR2 operates using its internal clock generator module (ICG), which provides stable 8 MHz bus frequency without external crystals or resonators. Pins PTC3/OSC2 and PTC4/OSC1 are unused in default configuration. External oscillators may be added only if higher precision timing is required beyond ICG specifications.

What LIN baud rates and slew rates are supported by MM908E624AYPEWR2?

MM908E624AYPEWR2 supports standard LIN baud rates up to 20 kbps with three programmable slew rates: normal (≤50 μs propagation), slow (≤100 μs), and fast (15 V/μs). Slew rate selection is configured via SPI register writes and complies with ISO 17987-2/4 for electromagnetic compatibility in automotive wiring harnesses.
