U2270B Datasheet | TEMIC Semiconductors

Read / Write Base Station IC Description IC for IDIC® - ) read-write base stations The U2270B is a bipolar integrated circuit for read-write base stations in contactless identification and immobilizer systems. The IC incorporates the energy transfer circuit to supply the transponder. It consists of an on-chip power supply, an oscillator, and a coil driver optimized for automotivespecific distances. It also includes all signal-processing circuits which are necessary to form the small input signal into a microcontroller-patible signal. The U2270B is well suitable to perform read operations with e5530-GT and TK5530-PP transponders and also performs read-write operations with...
