Although the Freescale accelerometers contain internal performance or cause failure of the chip. When handling the 2kV ESD protection circuitry, extra precaution must be taken accelerometer, proper ESD precautions should be followed by the user to protect the chip from ESD. A charge of over to avoid exposing the device to discharges which may be 2000 volts can accumulate on the human body or associated detrimental to its performance. test equipment. A charge of this magnitude can alter the MMA2244KEG Sensors 2 Freescale Semiconductor, Inc.
