Product details

Overview

MM908E624ACPEW from NXP Semiconductors (formerly Freescale) is an integrated automotive-grade IC combining a HC08 microcontroller and SmartMOS analog control die in a single 54-pin SOICW package. It delivers triple high-side switch control (HS1–HS3), LIN physical layer interface, 5 V voltage regulator, current-sense op-amp, watchdog, and wake-up inputs - all optimized for relay-driven motor control in window lift, sunroof, and fan systems.

For engineers reviewing the MM908E624ACPEW datasheet, MM908E624ACPEW pinout, MM908E624ACPEW application, or MM908E624ACPEW equivalent, this page provides verified functional partitioning (MCU + analog die), LIN timing specs, HS R_DS(ON) values per channel, diagnostic capabilities (current sense, over-temp shutdown, fault flags), and validated alternative options for relay driver subsystems.

Technical Context

The MM908E624ACPEW implements a dual-die architecture: an M68HC908EY16 MCU core (8 MHz bus, 16 KB flash, 512 B RAM, 10-bit ADC, ESCI, SPI) co-packaged with a SmartMOS analog die featuring three independent high-side drivers, LIN transceiver, 5 V LDO regulator (110 mA typical output), and rail-to-rail current-sense amplifier (±25 mV offset, 1 MHz GBW).

Control flow is split across domains: MCU handles protocol stack, diagnostics, and SPI command sequencing; analog die executes real-time switching, thermal protection (latched shutdown at 155–190 °C), LIN bus signaling (recessive/dominant propagation ≤50 μs), and wake-up detection via L1/L2 inputs with programmable hysteresis (0.5–1.3 V).

Pinout & Package

MM908E624ACPEW uses a 54-pin SOICW (Small Outline Integrated Circuit, Wide) package with 0.8 mm lead pitch and exposed thermal pad. Pin numbering follows standard SOICW convention (pin 1 = top-left corner, counterclockwise). The device integrates two physically separate dies - MCU and analog - sharing common power/ground rails but with distinct pin assignments.

Pin/Terminal	Circuit Role	Design Meaning
HS1, HS2, HS3	High-side switch outputs	Low-R_DS(ON) power outputs driving relays/motors; each includes independent over-temp and over-current protection with latched fault flag
LIN	LIN bus transceiver I/O	Single-wire bidirectional interface; drives/receives ISO 9141-2/17987 signals; includes internal pull-up (20–60 kΩ) and wake-up deglitcher (35–150 μs)
PWMIN	Direct HS1/HS2 enable & PWM input	Allows external PWM control of HS1/HS2 without MCU intervention; logic-high enables switches, duty cycle modulates average current

+E, −E, OUT	Current sense amplifier terminals	+E/−E connect across shunt resistor; OUT delivers amplified differential voltage (gain = 20 V/V typical) for MCU ADC monitoring
RST_A, IRQ_A	Analog die status outputs	RST_A asserts low on analog die reset; IRQ_A pulses low on fault (over-temp, over-current) or wake-up event - both readable via MCU GPIO
VSP1, VSP	SmartMOS power supply inputs	VSP1/VSP accept battery input (5.5–27 V); feed internal regulator and high-side drivers; support ISO 7637 pulse immunity up to ±100 V

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side relay driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC33883A	Single high-side switch (not triple); no embedded MCU; requires external microcontroller and LIN transceiver	Used in simpler relay nodes where MCU functionality is handled externally; lacks integrated current sense amplifier and wake-up inputs	Choose when only one high-side channel is needed and system already includes a LIN-capable MCU; lower integration but higher flexibility in firmware design
MC33972	Quad high-side driver with SPI interface (no LIN PHY); includes watchdog and current sense but no embedded MCU core	Designed for CAN-based systems; supports higher voltage (40 V) and current (600 mA/channel); lacks LIN physical layer and on-chip flash memory	Prefer for CAN networks or applications requiring >27 V operation; requires external CAN controller and separate 5 V regulator

Compared with MM908E624ACPEW, MC33883A offers lower integration but greater design modularity, while MC33972 provides higher channel count and voltage rating at the cost of LIN compatibility and MCU autonomy - making MM908E624ACPEW uniquely suited for cost-sensitive, space-constrained LIN body electronics nodes.

FAQ

What is the maximum operating junction temperature for MM908E624ACPEW?

The MM908E624ACPEW has a guaranteed parametric operating junction temperature range of −40 °C to +125 °C. The analog die thermal shutdown activates at 155–190 °C (latched off), but sustained operation above 125 °C voids specification compliance. Derating curves and thermal resistance data (θ_JA ≈ 40 °C/W) are provided in the Freescale datasheet Rev. 11.0 to support board-level thermal design for MM908E624ACPEW.

Does MM908E624ACPEW support direct PWM control of its high-side outputs without MCU involvement?

Yes, MM908E624ACPEW supports direct PWM control via the PWMIN pin, which independently enables or disables HS1 and HS2. When PWMIN is asserted high, HS1/HS2 follow the logic state of their respective control registers; when PWMIN is low, both outputs are forced off regardless of register state. This allows external microcontrollers or timers to modulate motor current without firmware intervention - a key feature confirmed in the Functional Description section of the MM908E624ACPEW datasheet.

How does the current sense amplifier in MM908E624ACPEW interface with the onboard ADC?

The current sense amplifier in MM908E624ACPEW outputs a buffered, amplified differential voltage on the OUT pin, referenced to VCC (5 V). This analog signal connects directly to any of the MCU's 10-bit ADC input channels (e.g., PTA0–PTA4, PTB0–PTB7). With typical gain of 20 V/V and ±25 mV input offset, the amplifier enables resolution of ~10 mA current steps across a 100 mΩ shunt - a capability explicitly supported by the MM908E624ACPEW's integrated ADC architecture and verified in the Electrical Characteristics tables.

Can MM908E624ACPEW operate with battery voltages below 9 V?

Yes, MM908E624ACPEW supports functional operation down to 5.5 V supply (VSUP), with guaranteed specifications from 9.0 V to 16 V. Below 9 V, certain parameters degrade: high-side R_DS(ON) increases, regulator dropout rises, and LIN bus timing margins narrow. The device remains operational at 5.5 V (e.g., during cranking), but users must validate timing, current limits, and thermal behavior per the Static Electrical Characteristics table in the MM908E624ACPEW datasheet Rev. 11.0.

What LIN protocol versions and data rates does MM908E624ACPEW support?

MM908E624ACPEW implements the LIN physical layer compliant with ISO 9141-2 and ISO 17987-4, supporting standard LIN 1.x and 2.x frame formats. It operates at baud rates up to 20 kbps with guaranteed timing (≤50 μs propagation delay) under normal slew rate conditions. The MCU's ESCI module handles protocol stack execution; physical layer timing and bus wake-up behavior are fully characterized in the Dynamic Electrical Characteristics section of the MM908E624ACPEW datasheet.
