SCA630-EDCV1B Datasheet SCA630-EDCV1B SINGLE AXIS ACCELEROMETER WITH ANALOG INTERFACE The SCA630 accelerometer consists of a silicon bulk micro machined sensing element chip and a signal conditioning ASIC. The chips are mounted on a pre-molded package and wire bonded to appropriate contacts. The sensing element and ASIC are protected with silicone gel and lid. The sensor has 8 SMD legs (Gull-wing type). Applications Features ? Single +5 V supply SCA630 product family is targeted to automotive ? Current consumption 2.5 mA typical applications with high stability and reliability ? Ratiometric output in relation to supply requirements. Typical applications include: voltage (Vdd = 4.75 V...5.25 V) ? Electronic Stability Control (ESC) ? Enhanced failure detection features ? Engine Vibration Measurement o Digitally activated, true self-test by ? Roll Over proof mass deflection using ? Suspension electrostatic force o Memory parity check during power ? Inclination up, and self-test cycle. o Built in connection failure detection ? Digitally activated, true self-test by proof mass deflection using electrostatic force ? Wide load drive capability (max. 20 nF) ? True DC response? ? Qualified according to AEC-Q100 standard 5V supply Gain & Measurement filtering Vout circuitry Sensing EEPROM for calibration element Digital self constants (32 bit, pari ty check) test input ASIC 4 programming lines GND for factory use only Figure 1.
