Read/Write Base Station

U2270B

The U2270B is an IC 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 automotive-specific distances. It also includes all signal-processing circuits which are necessary to transform the small input signal into a microcontroller-compatible signal.
