KXTC9-2050

**PART NUMBER: ±  2g Tri-axis Analog KXTC9-2050 Accelerometer Specifications Rev. 2 Feb-2015** 

## **Product Description** 

The KXTC9-2050 is a Tri-axis, silicon micromachined accelerometer with a full-scale output range of +/-2g (19.6 m/s/s). The sense element is fabricated using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on the principle of a differential capacitance arising from acceleration-induced motion of the sense element, which further utilizes common mode cancellation to decrease errors from process variation, temperature, and environmental stress. The sense element is hermetically sealed at the wafer level by bonding a second silicon lid wafer to the device using a glass frit. A separate ASIC device packaged with the sense element provides signal conditioning and self-test. The accelerometer is delivered in a 3 x 3 x 0.9mm Land Grid Array (LGA) plastic package operating from a 1.8 – 3.6V DC supply.  The KXTC9 features a factory programmable low pass filter. 

There are 2 factory programmable modes of operation for the KXTC9: 

**Mode 00** – The Enable pin must be **high** for normal operation and **low** for power shutdown. 

**Mode 01** – The Enable pin must be **low** for normal operation and **high** for power shutdown. 

The KXTC9-2050 is factory programmed to be in MODE 00.

## **Power-On Reset (POR)** 

Proper functioning of power-on reset (POR) is dependent on the specific **VDDLow** and **TVdd_Off** profile of individual applications.  It is recommended to minimize **VDDLow** and maximize **TVdd_Off** .  To assure proper POR in all environmental conditions the application should be evaluated over the range of **VDDLow** , **TVdd_Off** and temperature as POR performance can vary depending on these parameters.  It is also advised that the Rise or Fall be monotonic.  Note that the outputs will not be stable until **VDD** has reached its final value. 

Specific application testing will likely demonstrate POR performance regions for a proper POR trigger. To assure POR trigger properly executes, setting operational thresholds consistent with Table 3 below is suggested. 

## **Example POR performance chart** 

As can be seen in this example POR performance chart, the time and Voltage to activate POR is variable depending on the voltage and time as indicated by **TVdd_Off** max and min and **VDDHigh** and **VDDLow** .

## Notes: 

1. VDD must always be monotonic ramps without ambiguous state. 

2. TVdd rise or fall from 10% to 90% of final value needs to be ≤ TVdd Max. 

3. In order to prevent the accelerometer from entering an ambiguous state, VDD needs to be pulled down to GND ( ≤ VDDLow Min for a duration of time ≥ TVdd_Off Min) 

4. Power will be maintained if VDD does not go below VDDHigh Max. 

5. Between VDDHigh Max and VDDLow POR may occur.

It is important the user determines the timing ( **TVdd_Off** ) and threshold ( **VDDLow** ) levels by evaluating the performance in the specific system for which the device will be incorporated. 

The data provided by Kionix is intended for initial customer design guidance only.  Kionix POR testing looks at a finite number of test configurations.  Each customer application will have varying input sensor parameters (electrical, mechanical, and environmental) that will be different than the configurations tested by Kionix.  Each customer utilizing the sensor will need to properly validate the sensor (including POR function) within their application under their specific use cases to ensure it responds as required.

## **Application Design Equations** 

The bandwidth is determined by a factory programmable switched capacitor filter. The filter can be set at the factory to be 2kHz, 1kHz, 500Hz, 100Hz, 50Hz, or no low pass filter. Alternatively, bandwidth can be reduced by addition of a capacitor on the output pins 5, 6, and 7 according to the equation:
