Application Notes

  • TMS3705 Passive Antenna Solution
    PDF, 454 Kb, File published: Jul 12, 2010
    The Texas Instruments low-frequency transponder technology provides the possibility to use a simple passive antenna in combination with various antenna cable lengths. This solution significantly reduces system costs because the active part of the transceiver can be added to the already existing host system, e.g., the body control module (BCM) of a vehicle.In comparison to a standard system, n

  • Resonant Trimming Sequence
    PDF, 88 Kb, File published: Jan 9, 2013
    This application report presents an efficient and precise method on how to achieve the desired resonant frequency of configuring the trim array with only a few iterations and measuring the resonant frequency. First, the minimum and maximum resonant frequency is measured; from this data a capacitance gradient is derived, which allows a good prediction of the required capacitance. The calculated cap
  • TMS3705 Range Extender Power Solution Using UCC27424-Q1
    PDF, 396 Kb, File published: Aug 9, 2012
    This application report provides supplementary information about the Texas Instruments 134.2 kHz RFID Base Station IC TMS3705x in combination with an external driver IC. In particular, the document shows a low cost and easy-to-implement solution to improve the communication distance between the transaction processor (TRP) and the Reader unit.
