Functional Description

4.3.4

Undervoltage on the Digital Supply

If the voltage on

IO supply input falls below the threshold VIO < VIO(UV,F), the transceiver TLE7251V powers down

and changes to the power-down state.

The undervoltage detection on the digital supply

IO has the highest priority. It is independent of the transmitter

supply

CC and also independent of the currently selected operating mode. An undervoltage event on VIO always

powers down the TLE7251V.
