U2270B-MFP [Microchip]

U2270B-MFP Description

The U2270B-MFP is an IC for IDIC® 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.
