This base station IC drives the antenna of a TI-RFid transponder system to send data modulated on the antenna signal, and to detect and demodulate the response from the transponder. It allows also minimizing the external component count. The key functions of the base station IC TMS3705A are: » Self-adapting to transponders with a resonance frequency between 129 kHz – 140 kHz » Supports all TI-RFid LF transponder functions » Asynchronous and synchronous data transmission to the IC » Power management for 5V operation » Internal full bridge antenna driver » PLL for internal clock generation of 16 MHz » Overcurrent protection of antenna driver Specifications: Part Number RI-TMS3705ADR Operating Frequency Typical 134.2kHz, FSK Operating Voltage 4.5V to 5.5V DC Current Consumption Charge Phase (without antenna load) typical 8 mA; max. 20mA Sleep Mode (without I/O currents) typical 15 µA; max. 0.2mA Interface to Micro Controller Two wire multifunctional serial interface, 15625 baud Antenna Inductivity 400 µH - 700µH recommended ESD Protection (MILSTD 883) -2000V to +2000V Operating Temperature -40 °C to +85°C Storage Temperature -40 °C to +100°C (125°C up to 1000hrs over lifetime) Package / Pin count SO 16 (10 mm x 6 mm) Packing / Delivery Tape on Reel, 2500 units per reel Sample Set-up of a Transponder System For more information, contact the sales office or distributor nearest you.
