MMA6262QR2 개요
An accelerometer is a micro-electromechanical sensor (MEMS) that measures the proper acceleration acting on a mass and converts that mechanical deflection into an electrical signal proportional to g-force. In the broader sensor taxonomy the MMA6262QR2 belongs to motion sensors, then accelerometers, then linear (non-tilt-switched) accelerometers, then single-/dual-axis MEMS devices. These parts sit above simple inclinometers and below full 6-axis inertial measurement units (IMUs) that combine a 3-axis accelerometer with a 3-axis gyroscope.
Key features include signal conditioning on-chip, a g-select range fixed at ±1.5g, factory-set zero-g offset and full-scale span, low power consumption suitable for handheld and battery-powered equipment, and a -40 °C to +105 °C operating range that covers consumer and industrial environments. The integrated 150 Hz low-pass filter rejects high-frequency vibration and electrical noise without requiring external RC components.
The device uses a surface-micromachined capacitive sense element with a sigma-delta modulator and dedicated ASIC for ratiometric analog output. Because the sensitivity is ratiometric to VDD, the same part can be used at 3.0 V or 5.0 V supplies with the appropriate output scaling, simplifying multi-rail designs. The exposed pad (EP) on the QFN package provides a low-impedance thermal and electrical ground path that must be soldered for specified performance.
Typical applications include tilt and orientation sensing in handheld terminals, free-fall detection in hard-disk drives, motion-activated user interfaces, anti-theft / movement alarms, and vibration monitoring in industrial equipment. Its low current draw and small footprint also make it attractive for portable medical and fitness devices.
When designing with this part, solder the exposed pad to a continuous ground pour to achieve mechanical stability and the rated sensitivity. Avoid placing switching regulators or high-current traces near the sense element to prevent conducted EMI from corrupting the analog output. Decouple VDD with a 0.1 µF ceramic capacitor placed within 5 mm of the supply pin.

일반적인 애플리케이션
MMA6262QR2 적합 용도: 6 애플리케이션s: Hard-Disk Drive Free-Fall Detection, Handheld Tilt and Orientation Sensing, Anti-Theft and Movement Alarm, Industrial Vibration Monitoring, Motion-Activated User Interface, Portable Medical and Fitness Devices.
Hard-Disk Drive Free-Fall Detection
The MMA6262QR2's ±1.5 g range is well matched to the brief sub-1 g acceleration transient that occurs when a portable HDD is dropped, allowing the host controller to park the head within the 50-200 ms free-fall window. Its 150 Hz 1-pole low-pass filter rejects hand tremor and high-frequency vibration while passing the dominant free-fall energy band. Placed inside the HDD actuator bracket on a flexible mount, the X-axis senses vertical drop and Y-axis senses horizontal slip, both routed through the drive's existing shock sensor input. Unlike digital-output IMUs, the analog ratiometric output connects directly to legacy HDD controller ADCs without firmware changes, preserving backwards compatibility with installed HDD firmware bases.

Handheld Tilt and Orientation Sensing
With 740-860 mV/g sensitivity at 3.3 V supply, the MMA6262QR2 delivers approximately 1.6 V peak-to-peak swing across ±1.5 g - enough resolution to resolve sub-1° tilt changes after host-side scaling. The dual X/Y axis lets a handheld terminal detect portrait/landscape reorientation without a third Z-axis reference, simplifying firmware. The 16-QFN-EP (6x6) footprint fits inside the small PCB real estate behind LCD panels in portable data collectors. The ratiometric analog output pairs naturally with the SAR ADC inputs common to handheld microcontrollers, eliminating the need for a dedicated accelerometer digital interface. Designers should still mount the part on a rigid section of the PCB away from flex zones to avoid mechanical stress induced offset drift.

Anti-Theft and Movement Alarm
The MMA6262QR2's ±1.5 g range and 150 Hz bandwidth detect the gentle acceleration changes associated with an object being lifted or moved, making it ideal for bicycle alarms, package tampering sensors, and equipment-theft detectors. The dual X/Y axes provide directional information - whether the protected asset is being lifted vertically or carried horizontally - to discriminate authorized vs unauthorized motion patterns. Quiescent current in the sub-mA range supports multi-month battery operation when paired with a wake-on-motion host MCU duty cycle. The exposed pad (EP) on the QFN package must be soldered to a continuous ground pour so that mechanical shock to the PCB itself does not couple into the sense element as false motion.

Industrial Vibration Monitoring
The MMA6262QR2's integrated 150 Hz low-pass filter and capacitive MEMS sense element deliver a low-noise analog output suitable for monitoring low-frequency machine vibration in pumps, fans, and conveyor motors. With sensitivity of 740-860 mV/g at 3.3 V, the part easily resolves sub-100 mg vibration amplitudes when sampled by a 12-bit or 16-bit ADC. Operating from -40 °C to +105 °C, the accelerometer tolerates factory-floor temperature swings without recalibration. The dual X/Y axis allows simultaneous measurement of horizontal and vertical vibration modes from a single mount point, reducing sensor count on a vibration analytics node. Avoid mounting the sensor on flexible isolators where high-frequency resonance can alias into the 150 Hz filter passband.

Motion-Activated User Interface
The MMA6262QR2 provides the tilt-axis input for tap-to-wake, gesture-recognition, and shake-to-action user interfaces in remote controls and presentation clickers. Dual X/Y axes detect horizontal shake, vertical lift, and tilt gestures that a single-axis accelerometer cannot distinguish. The ratiometric analog output is read by a host MCU ADC at low sample rates (10-100 Hz), minimizing overall system power consumption for battery-powered remotes. Factory-calibrated zero-g offset eliminates the need for end-of-line calibration routines, reducing manufacturing cost. Designers should locate the part near the geometric center of the device housing to ensure consistent gesture sensitivity regardless of how the user holds the remote.

Portable Medical and Fitness Devices
The MMA6262QR2's small 16-QFN-EP (6x6) footprint and low quiescent current suit portable medical devices such as patient-activity monitors, fall-detection pendants, and step-counting wearables where PCB real estate and battery life are critical. The ±1.5 g range covers normal walking and stair-climbing acceleration peaks (typically 0.3-1.2 g), enabling activity classification without saturating the output. The integrated temperature compensation removes the need for periodic user calibration across body-temperature ranges. The dual X/Y axes can distinguish between walking (periodic vertical bounce) and stair climbing (mixed vertical/horizontal motion), supporting activity-classification firmware without adding a third sensor axis.

설계 노트
Solder the exposed pad (EP) of the 16-QFN-EP (6x6) package to a continuous ground pour. The EP is the primary mechanical anchor and ground reference; without proper soldering, sensitivity and offset drift increase substantially under thermal cycling or mechanical shock. Use at least 4 thermal vias under the EP to a bottom-layer ground plane for heat sinking and ground continuity. Avoid routing high-current switching traces directly under the sense element - the capacitive MEMS can pick up switching noise as false acceleration.
Decouple VDD with a 0.1 µF X7R ceramic capacitor placed within 5 mm of the supply pin. The MMA6262QR2's analog output is ratiometric to VDD, so any noise on the supply rail couples directly into the acceleration reading. For best noise performance add a 10 µF bulk capacitor near the supply pin and a ferrite bead between the bulk cap and the regulator output. Do not share the analog ground return with high-current digital loads - use a star ground topology.
Estimated: the MMA6262QR2's sensitivity scales with VDD as ~740 mV/g × (VDD/3.3 V). At 5 V supply the sensitivity rises to ~1120 mV/g, which can saturate downstream ADCs if the host firmware was calibrated for 3.3 V operation. Verify scaling math in host code against the actual VDD of the part, not the nominal 3.3 V. Also note that the package markings 'Contains Lead' per digchip.com may require lead-bearing solder processing on legacy lines.
Mount the MMA6262QR2 on a rigid section of the PCB, away from connector regions and screw bosses where flex or compression forces can couple into the sense element. The part's internal 150 Hz low-pass filter rejects high-frequency vibration but cannot reject low-frequency PCB bending. For best tilt-sensing accuracy, orient the part so the X-axis aligns with the device's natural tilt direction. Provide a keep-out zone (3 mm minimum) around the EP and sense element to prevent mechanical stress concentration.
