MMA2202D - ±56.3g X-Axis Micromachined Accelerometer | NXP
MPN: MMA2202D ✗ Akhir HidupMMA2202D Ringkasan
An accelerometer is a sensor that measures proper acceleration (the rate of change of velocity) along one or more axes, converting mechanical displacement of a proof mass into an electrical signal. The MMA2202D belongs to the single-axis MEMS accelerometer category, which is a subtype of motion sensor within the broader MEMS (micro-electro-mechanical systems) sensor family. MEMS accelerometers translate capacitive changes in a suspended silicon structure into voltage outputs via integrated ASIC signal conditioning.
Key features include ±56.3g dynamic range, 400 Hz bandwidth, ratiometric analog interface (38-42 mV/g typical sensitivity), self-test pin, and AEC-Q100 automotive qualification. The integrated 4-pole low-pass filter reduces aliasing and external component requirements, while factory trimming eliminates the need for external calibration passives at the customer end.
The MMA2202D uses a surface-micromachined capacitive sensor cell whose capacitance changes as a proof mass deflects under acceleration. An on-chip ASIC converts this differential capacitance into a ratiometric analog voltage. The architecture provides high shock survivability (>2000 g) and stable output over the automotive temperature range of -40 °C to +125 °C.
Typical applications include automotive airbag deployment systems, electronic stability control, vehicle dynamics sensing, industrial vibration analysis, and appliance anti-vibration control. The ratiometric output enables simple ADC interfacing without precision voltage references.
When designing with this device, ensure decoupling capacitors are placed close to the supply pins and that the self-test pin is either grounded (normal mode) or driven per the datasheet pulse specification. The non-RoHS exempting stands because the part contains lead (per verified distributor data).

Aplikasi Umum
MMA2202D cocok untuk 6 aplikasis: Automotive Airbag Deployment System, Electronic Stability Control (ESC) Sensor Module, Industrial Vibration Monitoring, Vehicle Dynamics Sensing (Roll-Over Detection), Appliance Anti-Vibration Control, Military and Aerospace Shock Testing.
Automotive Airbag Deployment System
The MMA2202D's ±56.3g range and AEC-Q100 qualification make it a primary candidate for airbag crash-sensing modules. Its 400 Hz bandwidth captures the dominant frequency content of a frontal crash pulse, and the ratiometric analog output simplifies interface to airbag ECU ASICs. The factory-calibrated zero-g and self-test pin satisfy FMVSS/ECE crash-sensor reliability requirements, reducing module-level calibration to within typical airbag controller budgets.

Electronic Stability Control (ESC) Sensor Module
The MMA2202D can serve as a low-g confirmation accelerometer inside an ESC module, validating the primary high-g crash sensor. Its X-axis sensing axis aligns with vehicle longitudinal dynamics, and the 38-42 mV/g sensitivity yields ~2.5 V at 0 g with strong signal headroom at typical braking/lateral events. The SOIC-16 footprint supports reflow soldering on automotive PCB substrates and survives the -40 °C to +125 °C automotive grade range.

Industrial Vibration Monitoring
For industrial vibration monitoring of fans, motors, and rotating machinery, the MMA2202D's 400 Hz bandwidth covers most machine-vibration spectra up to several thousand RPM. Its 5 V ratiometric output can be sampled directly by a PLC analog module or industrial MCU ADC. The automotive-grade temperature range ensures operation in harsh factory environments, and the SOIC-16 package supports hand-soldering for retrofit installations on legacy equipment.

Vehicle Dynamics Sensing (Roll-Over Detection)
Roll-over detection systems use a single-axis accelerometer mounted vertically to detect tilt-induced lateral acceleration. The MMA2202D's X-axis sensitivity and ±56.3g range provide headroom for the extreme lateral g-forces during emergency maneuvers. The AEC-Q100 qualification and ratiometric output simplify integration with existing roll-over ECU hardware originally validated against NXP's MMA-series analog interface.

Appliance Anti-Vibration Control
Washing machines and other vibrating appliances can use the MMA2202D to detect unbalanced-load conditions during high-speed spin cycles. The accelerometer's ±56.3g range captures the transient shocks of unbalanced loads while the 400 Hz filter rejects high-frequency motor PWM noise. The 5 V supply rail is readily available in appliance controllers, and the surface-mount package fits standard appliance PCB assemblies.

Military and Aerospace Shock Testing
The MMA2202D's wide bandwidth and ±56.3g range make it useful for shock and vibration testing of military hardware per MIL-STD-810. The robust SOIC-16 package handles mechanical stress during high-g shock events and survives the wide temperature excursions typical of field-deployed equipment. Although not formally MIL-spec qualified, the AEC-Q100 motor-grade build provides high reliability for non-critical military sensing applications.

Catatan Desain
Place a 0.1 µF ceramic decoupling capacitor as close as possible to the VDD pin and a bulk 1-10 µF tantalum or ceramic capacitor on the same supply trace. The MMA2202D's ratiometric analog output scales with VDD; noise or drift on VDD will directly appear on the acceleration reading. Use a low-noise LDO such as a 78M05 if the upstream 5 V rail has significant switching noise.
Orient the MMA2202D SOIC-16 package so that the X-axis sensing direction is aligned with the application's intended acceleration axis. The X-axis arrow direction is documented in the NXP/Motorola datasheet mechanical drawing. Incorrect orientation will produce signals on the wrong axis and cause false triggering in airbag and stability-control algorithms.
The XOUT pin is a low-impedance analog output, but keep the PCB trace short and routed away from switching signals (motor drivers, PWM, RF). Route the trace over a continuous ground plane and use a guard trace if necessary. The 4-pole internal low-pass filter limits noise bandwidth to 400 Hz, but high-frequency interference can produce rectification artifacts in the output stage.
Do not connect the self-test (ST) pin to VDD permanently; drive it only with a momentary pulse per datasheet specification during test routines. Continuous ST assertion will corrupt the XOUT reading. Also, the MMA2202D is RoHS non-compliant (contains lead); use the lead-free MMA26xx family for new designs requiring RoHS compliance.
