The MEMSIC Digital Thermal Orientation Sensor (DTOS) is the world's first fully-integrated orientation sensor. Its operation is based on our patented MEMS-thermal technology and is built using a standard 0.18um CMOS process. This sensor contains no moving parts (such as a ball) and thus eliminates field-reliability and repeatability issues associated with competitive products. It also eliminates the "click" sounds typically heard in ball based orientation sensors. Shock survival is greater than 50,000g. This sensor detects four orientation positions, shake and shake direction. In addition, it provides X/Y axis acceleration signals with very low 0g offset.  An I2C interface is used to communicate with this device and an interrupt pin (INT) is provided for shake and orientation. The device also has a power down enabled through the I2C interface.
