Functional Description
4.3 Power-up and Undervoltage Condition
By detecting an undervoltage event, either on the transmitter supply VCC or the digital supply VIO, the transceiver
TLE7250V changes the mode of operation. Turning off the digital power supply VIO, the transceiver powers down
and remains in the power-down state. While switching off the transmitter supply VCC, the transceiver either
changes to the forced power-save mode, or remains in power-save mode (details see Figure 5).
