SCA610-E28H1A SINGLE AXIS ACCELEROMETER WITH ANALOG
INTERFACE
The SCA610 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).
Features
Applications
• Single +5 V supply
• Current consumption 2.5 mA typical
• Ratiometric output in relation to supply
voltage (Vdd = 4.75 V...5.25 V)
• Enhanced failure detection features
o Digitally activated, true self-test by
proof mass deflection using
electrostatic force
o Memory parity check during power
up, and self-test cycle.
o Built in connection failure detection
• Digitally activated, true self-test by proof
mass deflection using electrostatic force
SCA610 product family is targeted to automotive
applications with high stability and reliability
requirements. Typical applications include:
• Electronic Stability Control (ESC)
• Engine Vibration Measurement
• Roll Over
• Suspension
• Inclination
• Wide load drive capability (max. 20 nF)
• True DC response
• Qualified according to AEC-Q100 standard
