Product details
Overview
MMA2206KEG from NXP Semiconductors (formerly Freescale) is a surface-mount, silicon capacitive, micromachined X-axis accelerometer with ±80g full-scale range, 4th-order Bessel low-pass filter (360–440 Hz), and integrated self-test, status monitoring, and temperature compensation. It delivers ratiometric linear analog output (18.6–21.4 mV/g/V) and operates across –40°C to +105°C for automotive-grade vibration and impact sensing.
For engineers reviewing the MMA2206KEG datasheet, MMA2206KEG pinout, MMA2206KEG application, or MMA2206KEG equivalent, key selection criteria include its factory-calibrated zero-g offset, 3.0–6.0 mA supply current, 110 mVRMS noise (10 Hz–1 kHz), AEC-Q100 Grade 2 qualification, and SOIC-16 package compatibility with industrial and automotive safety-critical systems.
Technical Context
The MMA2206KEG integrates a wafer-level hermetically sealed polysilicon g-cell transducer with a CMOS ASIC featuring switched-capacitor signal conditioning, on-chip 4-pole Bessel filter, and EPROM-trimmed calibration. Its architecture enables direct analog voltage output without external components while preserving pulse shape integrity via linear phase response.
Self-test is implemented using an electrostatic actuation plate that deflects the movable center plate under logic-high ST input, generating a calibrated 8.4–15.6 g-equivalent output shift. Fault detection includes low-voltage detect (2.7–4.0 V trip), clock monitor (50–260 kHz), and EPROM parity latch, reported via open-drain STATUS pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Full-Scale Range | ±80g - defines maximum measurable acceleration before saturation; supports high-shock impact monitoring. |
| Bandwidth (–3 dB) | 360–440 Hz - sets usable frequency limit for dynamic vibration analysis without aliasing. |
| Sensitivity | 18.6–21.4 mV/g/V - ratiometric gain enables stable measurement across VDD variations (4.75–5.25 V). |
| Output Noise (RMS) | 110 mVRMS (10 Hz–1 kHz) - determines minimum detectable acceleration resolution in low-amplitude applications. |
| Operating Temp | –40°C to +105°C - meets AEC-Q100 Grade 2 requirements for under-hood automotive environments. |
| Supply Current | 3.0–6.0 mA - enables low-power continuous monitoring in battery-backed or energy-constrained systems. |
| Self-Test Output Shift | 8.4–15.6 g-equivalent - provides deterministic mechanical-electrical verification without external stimulus. |
Pinout & Package
Package: 16-lead SOIC (Case 475-01), Pb-free (KEG suffix), surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–3, 9–13, 14–16 | No Connect (N/C) | Internally unconnected; must be left floating per layout guidelines to avoid parasitic coupling. |
| 4 (ST) | Digital Input | Active-high self-test trigger; internal pull-down prevents false initiation; requires ≥100 µs pulse for status reset. |
| 5 (VOUT) | Analog Output | Ratiometric voltage output (VDD/2 ± sensitivity × acceleration); requires 1 kΩ + 0.01 µF RC filter to suppress clock noise. |
| 6 (STATUS) | Open-Drain Fault Flag | Latches high on LVD, clock failure, or EPROM parity error; reset by ST pulse unless fault persists. |
| 7 (VSS) | Ground Reference | Primary power return path; must connect to solid ground plane beneath device per PCB layout rules. |
| 8 (VDD) | Power Supply | 4.75–5.25 V nominal; requires 0.1 µF decoupling capacitor placed adjacent to pin per layout guidance. |
Key Features
| Feature | Design Value |
|---|---|
| Wafer-level hermetic seal | Eliminates moisture-induced drift and long-term reliability degradation in harsh environments. |
| Onboard 4th-order Bessel filter | Preserves transient waveform fidelity for accurate shock pulse characterization without external components. |
| Factory-calibrated zero-g offset & sensitivity | Removes need for system-level trimming; ensures ±80g range accuracy over temperature and supply voltage. |

Applications
| Automotive Airbag Deployment Systems | Industrial Vibration Monitoring |
|---|---|
|
Use Scenario: Real-time crash pulse detection during frontal/side collisions to trigger pyrotechnic inflators within strict timing windows. IC Role / Device Role / Timing Role: Primary X-axis acceleration sensor providing analog voltage output to airbag control unit ADC; self-test validates readiness at power-up and periodically.

IC Role / Device Role / Timing Role: High-shock survivability sensor (1500 g powered, 2000 g unpowered) capturing transient acceleration peaks for structural health assessment. Use Value: Robust design withstands repeated 1500 g shocks; ±80g full-scale range resolves peak amplitudes with 12-bit+ effective resolution when digitized. |
Use Scenario: Embedding in shipping containers or pallets to record drop events (>1.2 m concrete drop test compliance) and rough handling during logistics. IC Role / Device Role / Timing Role: Event-triggered data logger front-end; STATUS pin signals fault conditions (e.g., low voltage) that could invalidate recorded data. Use Value: Self-test confirms functionality before shipment; wide –40°C to +105°C range covers global climate extremes; SOIC-16 allows compact PCB integration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMA2206EGR2 | Identical electrical and mechanical specifications; differs only in tape-and-reel packaging (MMA2206KEG is tube-packaged). | No functional difference; suitable for automated SMT assembly where reel format required. | Select MMA2206EGR2 for high-volume pick-and-place production; MMA2206KEG preferred for prototyping or low-volume builds. |
| ADXL206 | Wider ±100g range, higher 2.5 mA typical supply current, no integrated self-test or STATUS fault reporting; uses different 8-lead CERDIP package. | Lacks built-in diagnostics; requires external circuitry for system-level health monitoring. | Choose ADXL206 only if extended range outweighs need for self-test and fault flag; not drop-in due to pinout and package mismatch. |
Compared with MMA2206KEG, MMA2206EGR2 offers identical performance in reel format for production, while ADXL206 trades diagnostic capability for broader range and higher power-making MMA2206KEG optimal for safety-critical automotive and industrial systems requiring verified integrity.

FAQ
What is the operating voltage range for the MMA2206KEG?
The MMA2206KEG operates from 4.75 V to 5.25 V. Within this range, it functions as a fully calibrated linear accelerometer. Operation outside this window may yield linear output but without guaranteed calibration accuracy. The device includes low-voltage detection with a trip point between 2.7 V and 4.0 V, signaled via the STATUS pin.
How does the self-test function work on the MMA2206KEG?
The MMA2206KEG self-test applies electrostatic force to the movable g-cell plate via an internal fourth electrode when ST pin is driven high. This produces a calibrated 8.4–15.6 g-equivalent output shift at VOUT, verifying both mechanical deflection and signal chain integrity. A rising edge on ST also resets the latched STATUS flag if no active fault remains.
Is the MMA2206KEG pin-compatible with other devices in the MMA2206 family?
Yes, the MMA2206KEG shares identical pinout, package (SOIC-16, Case 475-01), and electrical interface with MMA2206EG, MMA2206EGR2, and MMA2206KEGR2. Differences are limited to packaging format (tube vs. reel) and manufacturing site; all variants use the same footprint and connection diagram.
What filtering is implemented in the MMA2206KEG and why is it important?
The MMA2206KEG integrates a 4th-order switched-capacitor Bessel filter with a –3 dB bandwidth of 360–440 Hz. Unlike Butterworth filters, Bessel topology provides maximally flat group delay, preserving pulse shape integrity-critical for accurate shock and impact event capture without waveform distortion.
Does the MMA2206KEG require external components for basic operation?
No external components are required for core operation, but recommended support circuitry includes a 0.1 µF VDD decoupling capacitor and a 1 kΩ + 0.01 µF RC filter on VOUT to suppress switched-capacitor clock noise. These values are specified in the datasheet and validated in the reference PCB layout.
