Product Summary

The TMS3763 is a LF base station IC. The TMS3763 allows efficient development and production of RFID readers for low power hand scanners, stationary readers and vehicle immobilizers. 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. The TMS3763 also allows minimizing the external component count.

Parametrics

TMS3763 absolute maximum ratings: (1)Operating Voltage: 4.5 to 5.5V; (2)Charge Phase (without antenna load): typical 8 mA; max. 20 mA; (3)Current Consumption; (4)Sleep Mode (without I/O currents): typical 15 mA; max. 0.2 mA; (5)ESD Protection (MILSTD 883, HBM ): -2000 to +2000 V; (6)Operating Temperature: -40 to +85℃; (7)Storage Temperature: -40 to +100℃ (125 up to 1000hrs over lifetime).
