TMS3705ADR

LF基站IC LF Base Station IC

The LF base station IC allows efficient development and production of RFID readers for vehicle immobilizers. This base station IC drives the antenna of a -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.

Key functions:

-  Low current consumption in sleep mode

-  Automatic transponder frequency measurement and adaptation

\-  Diagnosis function

-  Full bridge antenna driver

-  Built in band-pass filter and limiter

-  Digital FSK demodulator

-  High speed data transmission in synchronous mode

-  Power on reset

-  PLL

-  Short circuit protection

-  Support of all TI-RFID LF transponder functions
