MMA7360LR1 Overview
An accelerometer is a micro-electromechanical sensor (MEMS) that converts mechanical acceleration into an electrical signal. Three-axis (X, Y, Z) accelerometers sit at the bottom of the sensor hierarchy as motion sensors, branch upward into inertial measurement units (IMUs) when combined with gyroscopes, and ultimately form part of the broader sensor and signal-conditioning chain in embedded and industrial designs. The MMA7360 family was one of the earliest low-g analog-output 3-axis parts aimed at consumer and industrial tilt, motion, and freefall detection.
Key features include a 400 Hz X/Y and 300 Hz Z bandwidth, 0g-Detect freefall output, low 400 uA typical supply current, 2.2V to 3.6V supply range, and a 1.5 mA active self-test mode. The g-Select pin allows the host microcontroller to toggle between ±1.5g (high-resolution tilt sensing) and ±6g (shock/vibration sensing) ranges without hardware reconfiguration, while the 0g-Detect interrupt pin signals linear freefall - useful for hard-disk drop protection and portable-device sleep modes.
The MMA7360LR1 uses a surface-micromachined capacitive sense element with on-chip CMOS signal conditioning, providing a stable 0g offset over temperature and a ratiometric output that scales with supply voltage. The internal architecture combines a Wheatstone-bridge MEMS structure, charge-integrating amplifier, and bandgap reference, delivering low noise density and predictable temperature behavior across the -40C to +85C operating range.
Typical applications include tilt sensing in handheld electronics and appliances, freefall detection in laptops and removable storage, motion-activated user interfaces, vibration monitoring in industrial equipment, and gaming or remote-control inertial input. With its small 3x5 mm LGA footprint, the MMA7360LR1 is also a common choice for wearable prototypes and consumer IoT motion modules.
When designing with the MMA7360LR1, ensure decoupling capacitors are placed within 5 mm of the supply pin and route the analog outputs over a continuous ground plane to limit digital switching noise from coupling into the ratiometric output. The self-test pin should be exercised only after the part has fully powered up to avoid false triggering of the 0g-Detect line.

Typical Applications
MMA7360LR1 is suitable for 6 applications: Tilt Sensing in Handheld Electronics, Hard-Drive Drop Protection, Freefall Detection for Portable Devices, Motion-Activated User Interfaces, Industrial Vibration Monitoring, Appliance and White-Goods Tilt Safety.
Tilt Sensing in Handheld Electronics
The MMA7360LR1 is a strong fit for handheld tilt sensing thanks to its ±1.5g range, 800 mV/g sensitivity, and ratiometric analog outputs that scale with supply voltage. When mounted on a handheld device, gravity projects onto each axis so the host ADC can compute roll and pitch angles by trigonometry on the X/Y/Z outputs. The 14-LGA 3x5 mm footprint fits inside phone-sized enclosures, and the low 400 uA supply current makes it suitable for battery-powered tools and remotes. Designers should sample the analog outputs through oversampling and average out vibration noise below 50 Hz to improve tilt stability.
Recommended
Hard-Drive Drop Protection
The 0g-Detect freefall pin on the MMA7360LR1 enables fast drop detection for laptop hard-disk drives. When the laptop is dropped, all three axes simultaneously cross 0g, asserting 0g-Detect within milliseconds and giving the disk controller time to park the heads before impact. Operating from a 2.2V to 3.6V supply, the part runs directly off the laptop's 3.3V rail. The internal 1-pole low-pass filter attenuates high-frequency vibration that would otherwise cause false triggers, making it a reliable drop-protection sensor for legacy 2.5-inch HDD designs.
Recommended
Freefall Detection for Portable Devices
Portable electronics such as tablets, e-readers, and handheld scanners use the MMA7360LR1's 0g-Detect pin to implement drop-safe behavior. The ±6g selectable range (via g-Select) lets the host monitor high-g shocks that occur on landing. The 1.5 mA self-test current at 3.3V allows periodic verification of the MEMS element integrity without removing the device from the field. With the 400 Hz X/Y and 300 Hz Z bandwidth, the sensor captures both slow tumble events and sharp landing spikes within the same part.
Recommended
Motion-Activated User Interfaces
Consumer products such as TV remotes, game controllers, and presentation clickers use the MMA7360LR1 to wake from sleep on motion. The 400 uA active supply current plus internal sleep modes let the host MCU power down between gestures. The g-Select input lets designers use ±1.5g for fine tilt detection in menus and switch to ±6g for shake-to-activate gestures. Analog outputs connect directly to MCU ADCs, eliminating the need for an external signal-conditioning chain in low-cost human-interface devices.
Recommended
Industrial Vibration Monitoring
The MMA7360LR1's 400 Hz X/Y bandwidth and 300 Hz Z bandwidth cover the dominant frequency range of motor vibration and pump pulsation. Mounted on a motor housing, the analog outputs can be sampled by an industrial MCU or PLC ADC and FFT-processed for predictive maintenance signatures. The ratiometric output simplifies scaling, and the -40C to +85C operating range suits factory-floor enclosures. Designers should add an external anti-aliasing filter ahead of the ADC because the internal 1-pole filter is relatively gentle.
Recommended
Appliance and White-Goods Tilt Safety
Washing machines, robotic vacuums, and air conditioners use the MMA7360LR1 to detect tilt, tip-over, or unbalanced-load conditions. The 3-axis analog output lets the host detect both static tilt (gravity offset) and dynamic shock events. The wide 2.2V to 3.6V supply range accommodates noisy rectified-DC rails commonly found in appliances. The 14-LGA package's small footprint fits inside compact sensor modules mounted near the appliance's center of mass, and the robust -40C to +85C operating range handles warm mechanical environments.

Key Differentiators
- Selectable dual-range g-Select pin (vs MMA7330LR1 / MMA7340LR1)
- Dedicated 0g-Detect freefall pin (vs MMA7455LR1)
- Three ratiometric analog outputs with no MCU math overhead (vs MMA8451Q (digital))
Design Notes
Decouple VDD with a 0.1 uF ceramic capacitor placed within 5 mm of the supply pin, and add a 1 uF bulk capacitor on the host rail. The MMA7360LR1 draws 400 uA in normal operation and 1.5 mA during self-test - budget the LDO accordingly. Place the analog ground return directly to the board's ground plane rather than sharing a return with switching regulators, because ratiometric analog outputs will couple supply ripple directly into the measurement.
The 14-LGA package has an exposed pad that must be soldered to a grounded land pattern for thermal performance and mechanical reliability. Use NSMD (non-solder mask defined) pads and a 4-mil-to-6-mil solder paste stencil for the central thermal pad to ensure consistent reflow. Keep high-speed digital traces away from the XOUT, YOUT, and ZOUT lines; route the analog outputs over a continuous ground plane and avoid crossing power traces.
Do not enable the self-test pin until the supply has fully stabilized (typically 10 ms after Vdd crosses 2.2V), or the 0g-Detect line may assert falsely. The internal 1-pole low-pass filter is gentle; if your application needs sharper anti-aliasing, add an external RC network ahead of the host ADC. When switching between ±1.5g and ±6g via g-Select, allow at least one full output settling period before reading - the analog output can transiently clip during the range change.
Mount the MMA7360LR1 on a flat, rigid section of the PCB close to the device's center of mass for accurate tilt and drop measurement. Position the part so its X, Y, and Z axes align with the intended reference frame (Z is typically vertical through the package top). Avoid mounting near heat sources, speakers, or connectors that vibrate mechanically, since these couple into the MEMS element and bias the output.
