1. General Description
ATAK5276-83 is intended to demonstrate the performance of an LF wake-up channel
needed for battery-driven systems. Typical wake-up applications can be found in
vehicles for Tire Pressure Monitoring (TPM).
The demonstrator hardware (HW) consists of the LF transmitter board (ATAB5276)
patched onto a microcontroller base board and an LF receiver board (ATAB5283).
The high antenna driver ability of the transmitter, combined with the sensitive receiver,
enables a wake-up distance of up to 2.5 meters.
For the general functionality of the ATA5276 and the ATA5283 please refer to the
related datasheets.
