The ADXC1501 is a yaw rate gyroscope and three-axis
accelerometer combined in a single package. It is designed for
electronic stability control (ESC) and other high performance
applications that require yaw rate and acceleration signals
simultaneously. An internal temperature sensor compensates offset
and sensitivity performance, providing excellent stability over the
−40°C to +105°C temperature range.
A digital serial port interface (SPI) transmits the yaw rate and
acceleration data to a host microcontroller. A 4-bit cyclical
redundancy check (CRC) provides fault coverage for the
transmitted SPI data, and internal fault detection routines
ensure the integrity of all reported yaw rates and acceleration
data. A fully integrated electromechanical continuous self-test
(CST) routine provides run-time diagnostic capability for
assessing the health of each MEMS element.
An advanced gyroscope sensor design rejects the linear
acceleration effects of shock and vibration, enabling the
ADXC1501 to operate in harsh environments. The
accelerometer signal chain is designed to prevent overload
conditions from occurring in these same harsh environments.
The ADXC1501 is designed to operate at either 3.3 V or 5 V. At
less than 16 mA current consumption, the ADXC1501 can be
used in energy sensitive applications.
