8 / 17 page TPS22933A USB Port DC Input MSP430C3xx µC Switched Load Battery USB DC_IN BAT LOUT EN VOUT GND CAP TPS22933A USB Port DC Input Battery USB DC_IN BAT LOUT EN VOUT GND CAP Power Multiplexer Output TPS22933 SLVSB34 – OCTOBER 2011 www.ti.com APPLICATION EXAMPLES Below are two diagrams of typical applications for the TPS22933A. In all cases, the unused power inputs can be left floating or tied to ground. The EN pin must not be left floating. Figure 4 shows three power inputs multiplexed to source the LDO. The LDO always on output (LOUT) is tied to an MSP430. The MSP430 then determines when to enable the switched output (VOUT) by driving the EN pin. Figure 5 shows three power inputs multiplexed to source only through the CAP pin. In this case, the LDO outputs are not used (EN is tied low). The highest of the inputs is chosen to drive the voltage at the CAP pin. Note that these two applications are not mutually exclusive. An application could use the CAP pin as a power output and use one or both of the LDO outputs. Figure 4. Application Example 1 Figure 5.
