MMA6262QR2-FR Overview
A micromachined accelerometer is a MEMS (Micro-Electro-Mechanical Systems) sensor in which a proof mass suspended by compliant springs moves under acceleration, changing the capacitance between interdigitated comb fingers; that capacitance change is converted to an analog voltage by an on-chip ASIC. In the system hierarchy this device sits at: accelerometer -> motion sensor -> inertial measurement unit (IMU) building block -> MEMS sensor -> semiconductor. The same family of Freescale/NXP parts (MMA62xx) is widely used as a low-cost tilt, vibration, and motion-detection front-end.
Key specifications for the MMA6262QR2-FR include a sensitivity of 800 mV/g (typical), 0 g offset trimmed at the factory, a -3 dB bandwidth of 150 Hz set by the internal 1-pole RC filter, and a low 2 mA typical supply current from a single 2.2 V to 3.6 V rail. The ratiometric analog output scales with VDD, allowing direct ADC interfacing without a precision reference. Robustness features include shock survival up to 2000 g, ESD protection on all pins, and self-test capability via an external logic input that deflects the proof mass for in-system verification.
The exposed thermal pad on the QFN-16 package provides both a low-impedance ground return and a thermal path that improves long-term zero-g bias stability. The package is Pb-free and RoHS compliant, and the part is qualified over the -40 °C to +105 °C extended industrial range, making it suitable for harsh-environment designs. Typical output noise density is on the order of 350 µg/√Hz, sufficient for tilt, vibration, and free-fall detection but not for high-precision inertial navigation.
Common applications include HDD free-fall detection, tilt and orientation sensing in consumer electronics, vibration monitoring in industrial equipment, gaming controllers and pointing devices, and appliance anti-vibration control. The MMA6262QR2-FR is well suited where low cost, small footprint, and dual-axis analog output outweigh the need for higher bandwidth or digital I²C/SPI interfaces.
A key design consideration is the analog output architecture: because the output is ratiometric to VDD, the host ADC must use the same VDD as its reference, or the absolute acceleration reading will not be accurate. Place a 0.1 µF decoupling capacitor within 5 mm of the VDD pin and connect the exposed pad to a clean ground plane to minimize supply-referred noise and bias drift.

Typical Applications
MMA6262QR2-FR is suitable for 6 applications: HDD Free-Fall Detection in Portable Computers, Tilt and Orientation Sensing in Consumer Electronics, Vibration Monitoring in Industrial Equipment, Gaming Controllers and Pointing Devices, Appliance Anti-Vibration and Load-Balancing Systems, Automotive Security and Tilt Alarms.
HDD Free-Fall Detection in Portable Computers
The MMA6262QR2-FR is widely used as the free-fall sensor in laptop hard-disk-drive assemblies where it must detect acceleration transients smaller than 0.5 g within a few milliseconds so the drive head can be parked before impact. The ±1.5 g full-scale range gives ample headroom for the small free-fall signals while the 800 mV/g sensitivity produces a several-hundred-millivolt output swing that is easily digitized by the embedded controller. The 150 Hz internal 1-pole low-pass filter rejects high-frequency mechanical noise from the drive spindle and chassis vibration. Compared to discrete piezoelectric shock sensors, the MMA6262QR2-FR's 2 mA supply current and 6x6 mm QFN-EP footprint keep board area and battery drain minimal in mobile designs.
Recommended
Tilt and Orientation Sensing in Consumer Electronics
The MMA6262QR2-FR's dual-axis analog output measures gravity directly, making it ideal for tilt, portrait/landscape, and orientation detection in mobile phones, remote controls, and handheld appliances. With sensitivity of 800 mV/g and a ratiometric VDD/2 zero-g output, the sensor's X and Y outputs move a few hundred millivolts for small tilt angles and full ±400 mV at ±90°. The 150 Hz bandwidth is fast enough to follow typical user-driven tilt motion but slow enough to ignore hand-tremor noise. The exposed thermal pad of the QFN-EP package improves long-term zero-g bias stability, which is critical when calculating tilt angles from the static 1 g gravity vector.
Recommended
Vibration Monitoring in Industrial Equipment
Industrial machinery health-monitoring systems use the MMA6262QR2-FR to capture vibration signatures on motors, pumps, and fans. The dual-axis output allows monitoring of vibration in two orthogonal directions from a single sensor, while the analog ratiometric interface simplifies integration with existing 4-20 mA or 0-10 V analog acquisition modules. Although the 150 Hz internal filter limits high-frequency vibration analysis, the sensor is well suited to monitoring low-frequency bearing wear (typically <100 Hz) and imbalance faults. The 2000 g mechanical shock survival rating protects the MEMS element during incidental impacts during installation.
Recommended
Gaming Controllers and Pointing Devices
Game console controllers, motion-sensing remote controls, and electronic pointing devices rely on the MMA6262QR2-FR for tilt-based cursor steering and gesture input. The ±1.5 g range accommodates fast wrist-flick gestures without saturation, and the 800 mV/g sensitivity translates small hand motions into measurable analog voltages. The 150 Hz internal bandwidth is sufficient for gesture recognition algorithms while rejecting high-frequency RF interference from nearby wireless radios. The low 2 mA supply current extends battery life in wireless controllers.
Recommended
Appliance Anti-Vibration and Load-Balancing Systems
Washing machines, dryers, and similar appliances use the MMA6262QR2-FR to detect drum imbalance and excessive vibration during spin cycles. The dual-axis accelerometer measures both radial and tangential drum motion, while the analog ratiometric output interfaces directly with the appliance's motor-control MCU. The -40 to +105 °C operating temperature range tolerates the hot under-cabinet environment, and the 16-QFN-EP package withstands the mechanical shock of unbalanced loads. Compared to electromechanical vibration switches, the MMA6262QR2-FR allows software-configurable thresholds and gentle-load-detection algorithms.
Recommended
Automotive Security and Tilt Alarms
Aftermarket car alarms and trailer-tilt alarms use the MMA6262QR2-FR to detect vehicle jacking-up attempts, trailer tipping, or tow-truck hookup. The ±1.5 g range captures the small static tilt changes associated with one wheel being lifted while ignoring normal road vibration. The low quiescent current (2 mA) keeps standby battery drain low in always-on alarm applications. The exposed-pad QFN-16 footprint withstands under-dash temperatures up to +105 °C. Note: this part is not AEC-Q100 qualified, so for OEM automotive designs a qualified part such as the NXP FXLS8471Q should be selected.

Key Differentiators
- Factory-trimmed zero-g offset, full-scale span, and filter cutoff eliminate external trim components (vs MMA6801KWR2)
- Highest sensitivity in the ±1.5 g MMA6200 family at 800 mV/g (vs MMA6260QR2 / MMA6261QR2)
- Integrated on-chip self-test capability via external ST pin (vs Discrete piezoelectric shock sensors)
Design Notes
Place a 0.1 µF ceramic decoupling capacitor within 5 mm of the VDD pin to suppress supply noise. Because the MMA6262QR2-FR analog output is ratiometric to VDD, any noise on VDD couples directly into the measured signal. A low-noise LDO such as the MAX150ACPP feeding the sensor VDD will improve tilt measurement stability.
Do NOT use a precision voltage reference as the host ADC reference when reading the MMA6262QR2-FR output. The output is ratiometric, so the ADC must reference the same VDD that powers the sensor - otherwise gain errors of 5-10% will appear. The self-test pin must be left floating or tied low during normal operation; driving it high deflects the proof mass for diagnostic checks.
Connect the exposed thermal pad (EPAD) of the QFN-16 package to a clean ground plane with at least 4 thermal vias to the inner ground layer. The EPAD provides both the electrical ground return and the thermal path that keeps the MEMS die at a stable temperature. Poor EPAD soldering causes zero-g bias drift and degrades long-term accuracy.
Compliance Information
RoHS compliant per Freescale/NXP product page. Not AEC-Q100 qualified - select FXLS8471Q or similar qualified part for OEM automotive designs. Some MMA6200 series variants historically contained lead - confirm the specific MPN datasheet before RoHS-sensitive assembly.
