LY550ALH STMicroelectronics

LY550ALH MEMS motion sensor: high performance 500 /s analog yaw-rate gyroscope Preliminary data Features 2.7 V to 3.6 V single-supply operation Wide operating temperature range (-40 C to +85 C) LGA-16L (5x5x1.5mm) High stability overtemperature Analog absolute angular-rate output The LY550ALH has a full scale of 500 /s and is Two separate outputs capable of detecting rates with a -3 dB bandwidth (1x and 4x amplified) up to 140 Hz. Integrated low-pass filters The gyroscope is the combination of one actuator and one accelerometer integrated in a single Low power consumption micromachined structure. Embedded power-down It includes a sensing element composed by single Embedded self-test driving mass, kept in continuos oscillating High shock and vibration survivability movement and able to react when an angular rate ECOPACK RoHS and Green compliant is applied based on the Coriolis principle. (see Section 5) A CMOS IC provides the measured angular rate to the external world through an analog output Applications voltage, allowing high level of integration and production trimming to better match sensing Gaming applications element characteristics. Pointing devices, remote and game controllers STs gyroscope family leverages on robust and Motion control with user interface mature manufacturing process already used for Industrial and robotics the production of micromachined accelerometers. ST is already in the field with several hundreds Description million sensors with excellent acceptance from the market in terms of quality, reliability and The LY550ALH is a low-power single-axis performance. micromachined gyroscope capable of measuring LY550ALH is provided in plastic land grid array angular rate along yaw axis. (LGA) package. Several years ago ST pioneered It provides excellent temperature stability and successfully the usage of this package for high resolution over an extended operating accelerometers. Today ST has the widest temperature range (-40 C to +85 C). manufacturing capability and strongest expertise in the world for production of sensor in plastic LGA package. Table 1.
