Application Information
Figure 9 illustrates an FXLA2203 used in a dual-mode /
dual-SIM application. The FXLA2203 does not contain
any internal LDOs. Instead, the FXLA2203 architecture
incorporates two low-RON internal power switches for
routing existing Power Management Integrated Circuit
(PMIC) LDOs to individual SIM slot VCC pins.

CH_Swap Truth Table
CH_Swap controls simultaneous communication between Host
1 or Host 2, and either SIM Card according to Table 2 —
Dual-Mode, Dual-SIM Truth Table. Either host can swap
SIM slots (130ns typical) with the assertion of the
CH_Swap pin. This simple solution is faster and less
complicated than SPI or I
2C communication protocols.
