APPLICATION INFORMATION
Some applications have two energy sources, one of which should be used in preference to another. Figure 14
shows a circuit that will connect IN1 to OUT until the voltage at IN1 falls below a user-specified value. Once the
voltage on IN1 falls below this value, the TPS211xA will select the higher of the two supplies. This usually means
that the TPS211xA will swap to IN2.
Figure 14. Auto-Selecting for a Dual Power-Supply Application
In Figure 15, the multiplexer selects between two power supplies based upon the EN1 logic signal. OUT
connects to IN1 if EN1 is logic '1'; otherwise, OUT connects to IN2. The logic thresholds for the D1 terminal are
compatible with both TTL and CMOS logic.
