NXP Semiconductors MMA2202EG

Overview

MMA2202EG from Freescale Semiconductor is a surface-mount, silicon capacitive micromachined accelerometer with integrated signal conditioning, factory-calibrated ±50g full-scale range, 4th-order Bessel low-pass filter (f_–3dB = 360–440 Hz), and ratiometric linear output. It operates across –40°C to +125°C, draws 4.0–6.0 mA at 4.75–5.25 V, and delivers self-test verification and fault detection via STATUS pin - used in hard drive protection, appliance control, and vibration monitoring systems.

For engineers reviewing the MMA2202EG datasheet, MMA2202EG pinout, MMA2202EG application, or MMA2202EG equivalent, this page provides verified technical context including SOIC-16 pin mapping, calibrated self-test response (10–12 g), LVD trip threshold (2.7–4.0 V), clock monitor fail detection (150–400 kHz), and AEC-Q100 Grade 2 qualification for automotive-grade reliability.

Technical Context

The MMA2202EG integrates a polysilicon g-cell transducer hermetically sealed at wafer level with a CMOS ASIC performing switched-capacitor sensing, temperature compensation, and 4-pole Bessel filtering. Its ratiometric architecture ensures output offset (2.35–2.65 V) and sensitivity (0.46–0.54 V/V_DD) scale linearly with supply voltage, enabling robust ADC interfacing without external reference.

Self-test activation applies electrostatic force to the movable plate, inducing a calibrated 10–12 g mechanical deflection verified by STATUS pin latching. Fault detection monitors low-voltage condition (VLVD), clock oscillator frequency (f_min = 150 kHz), and EPROM parity - all reported via open-drain STATUS output requiring external pull-up.

FAQ

What is the operating temperature range for the MMA2202EG?

The MMA2202EG is specified to operate from –40°C to +125°C and is qualified per AEC-Q100 Rev. F Grade 2. This rating covers full electrical performance including sensitivity, offset, and self-test response across the entire range - validated for under-hood automotive and harsh industrial environments. The MMA2202EG maintains its ±50 g range and 360–440 Hz bandwidth throughout this span.

Does the MMA2202EG require external components for basic operation?

No, the MMA2202EG requires only a 0.1 μF decoupling capacitor on VDD and an RC filter (1 kΩ + 0.01 μF) on VOUT to suppress clock noise - all other functions including filtering, temperature compensation, and self-test are fully integrated. The MMA2202EG does not need external resistors, capacitors, or trim components to achieve factory-calibrated performance.

How does the STATUS pin function on the MMA2202EG?

The STATUS pin on the MMA2202EG is an open-drain output that latches high upon detection of low supply voltage (below 2.7–4.0 V), clock oscillator failure (frequency <150 kHz), or EPROM parity error. It remains asserted until a ≥100 μs high pulse is applied to the ST pin - provided the fault condition has cleared. The MMA2202EG STATUS pin thus serves as a persistent hardware-level fault indicator for system diagnostics.

Is the MMA2202EG pin-compatible with other devices in the MMA220x family?

Yes, the MMA2202EG shares identical SOIC-16 pinout and footprint with MMA2201EG and MMA2202KEG, including N/C pin locations, ST, VOUT, STATUS, VSS, and VDD assignments. All variants use Case 475-01 packaging and require the same PCB layout - enabling drop-in replacement where range or qualification differences permit.

What is the self-test capability of the MMA2202EG and how is it verified?

The MMA2202EG provides a calibrated electrostatic self-test that produces a 10–12 g mechanical deflection of the sensing element, resulting in a corresponding step change in VOUT. Verification is confirmed by monitoring the STATUS pin, which asserts high during self-test activation and remains latched if faults occur. This dual-path check ensures both mechanical and electronic integrity of the MMA2202EG without external test equipment.
