  • Page 4: Introduction

    The design is not qualified regarding manufacturing and operation over the whole operation temperature range or lifetime. This evaluation kit provided by TDK is intended to be used for functional testing only. Due to their purpose, evaluation driver kits are not intended to be used by the same procedures regarding returned material analysis (RMA) and process change notification (PCN) as regular products.

  • Page 9: Use Upi Feature

    (refer to section DIP Switch settings)   It is of utmost importance to not use the TDK PowerHap™ actuators in full-scale mode as it can get damaged unless the waveform is properly designed to limit the output voltage between -10 V and +60 V.
  • Page 10: Dip Switch Settings

    The output ranges listed for SW1 settings are for full amplitude input signal, for example -1 to +1 when using Audacity® software. When using TDK PowerHap™ 2.5G piezo actuator, set SW1 to OFF. More precisely, this switch sets the maximum and minimum values allowable for the selected range. It does not affect the gain and offset conversion between the input signal and the output voltage.

The balance between channels A and B can be changed using the "L/R" dial in the "Audio Track" field, L corresponding to channel A, R to channel B. The gain can also be changed with "-/+" dial, but beware of positive gains that may cause output clipping.

    Do not put values higher than 1.0 for any of those variables or it will permanently damage the piezo. These variables only have an effect when in TDK mode (SW1 OFF). In PSoCCreator, go to project “BOS1901_Test”, then go to folder “Header Files” and open file “sensing_button_data.h”.
