ATA5291

Status: In Production

Features:

  • Integrated PEPS driver and transponder immobilizer base station
  • Internal precision oscillator for carrier generation
  • IC power supply voltage from 6V to 28V for PEPS operation
  • IC power supply voltage from 4V to 28V for immobilizer operation
  • Fast SPI interface (2Mbit/s) for data access and configuration
  • Transparent data input and data output pinsData transmission and control buffers
  • Flexible commands set with LOOP and CALL capability allowing for programmable polling mode without the need to re-load the data buffer. This mode does not require any host controller interaction.
  • Flexible GPIO pin for control of peripherals independent of host
  • Very low power-down current consumption
  • QFN 7x7-48 with wettable flanks
  • LF carrier frequency 125kHz

Device Overview

Summary

An LF antenna driver device for passive entry/go (PEG) systems. It can drive up to eight low-frequency antennas (coils) to provide a wake-up and initialization channel to the key fob. Each driver is programmable up to a peak current of 1A (independent of battery voltage) and adjustable in 18 steps.
