Technical Documents for ROHM MEMs Accelerometers

Document Title Contents Brief Description
Package Handling, Mounting and Soldering Guidelines This technical note is intended to provide guidelines for the handling, mounting and soldering of Kionix's accelerometers. Component Handling - Physical Mounting Recommendations - Soldering Guidelines - De-Soldering / Re-Work This technical note is intended to provide guidelines for the handling, mounting, and soldering of Kionix’s sensors. These guidelines are general in nature and based on recommended industry practices. The user must apply their actual experiences and development efforts to optimise designs and processes for their manufacturing techniques and the needs of varying end-use applications.
PCB Design Guidelines for 2x2 LGA Accelerometers This technical note is intended to provide information about Kionix's 2 x 2 mm LGA packages and guidelines for developing PCB land pattern layouts. This technical note is intended to provide information about Kionix’s 2 x 2 mm LGA packages and guidelines for developing PCB land pattern layouts. These guidelines are general in nature and based on recommended industry practices.
Power on Procedure - KXTJ3 Accelerometers This technical note is intended to provide information about the proper power-on procedure of the Kionix KXTJ3 accelerometers. Proper functioning of power-on reset (POR) is dependent on the specific VDD, VDDLOW, TVDD (rise time) and TVDD_OFF profile of individual applications. It is recommended to minimize VDDLOW and TVDD and maximize TVDD_OFF. It is also advised that the VDD ramp up time TVDD be monotonic. To assure proper POR, the application should be evaluated over the customer specified range of VDD, VDDLOW, TVDD, TVDD_OFF and temperature as POR performance can vary depending on these parameters.
Power on Procedure - KX134 Accelerometers This technical note is intended to provide information about the proper power-on procedure for Kionix KX134 family of accelerometers. Proper functioning of power-on reset (POR) is dependent on the specific VDD, VDDLOW, TVDD (rise time) and TVDD_OFF profile of individual applications. It is recommended to minimize VDDLOW and TVDD and maximize TVDD_OFF. It is also advised that the VDD ramp up time TVDD be monotonic. To assure proper POR, the application should be evaluated over the customer specified range of VDD, VDDLOW, TVDD, TVDD_OFF and temperature as POR performance can vary depending on these parameters.
