Figure 12 Under - Voltage on V_IO or V_CC
7.3.2
Under - Voltage Event on V_S
If an under - voltage event is detected at the power supply V_S, the TLE6251-2G immediately transfers into the
Stand - By Mode, regardless of the operation mode in which the TLE6251-2G might currently operate. After the
power supply V_S has been reestablished, the operation mode can be changed by applying a logical “High” signal
to the EN pin or the NSTB pin.
In the case the TLE6251-2G detects an under - voltage event on the V_CC or V_IO power supply, the TLE6251-2G
changes to Sleep Mode. If the TLE6251-2G detects in Sleep Mode an under - voltage event on the V_S power
supply, the device changes to the Stand-By Mode, even if the under - voltage event on the V_CC or V_IO power supply
is still present.
