Utilizing the power shutdown capabilities of the Kionix tri-axis accelerometers

Kionix tri-axis accelerometers feature a power shutdown capability. Even with their typically low current draw, there are still applications that may require even less power consumption. For these applications, it is possible to implement a duty-cycle power-reduction methodology that uses a microprocessor to toggle the enable/disable pin or register at a specified duty-cycle. This approach can reduce greatly the accelerometer's current draw during the majority of its time in operation. This application note provides the theory and equations needed to take full advantage of this power saving capability.
