... Circuit) LDOs to individual SIM slots. This reduces overall system power, leverages existing LDO system resources, centralizing LDOs in the PMIC facilitates power management. Since the FXLA2203 does not block the LDO function to the SIM card, existing activation / deactivation timing transparency is maintained between Hosts, PMICs, and SIM cards. ...

... Application Information Figure 8 illustrates an FXLA2203 used in a dual-mode / dual-SIM application. The FXLA2203 does not contain any internal LDOs. Instead, the FXLA2203 architecture CH_Swap Truth Table CH_Swap controls simultaneous 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) © ...

... For example, if Host 1 operates at 1.65V and Host 2 operates at 2.5V, while slot respectively, while populated with a 3.0V SIM card and slot 2 is populated with a 1.8V SIM card, the FXLA2203 provides seamless voltage translation across all four V Figure 10.

... I/O pin, the rise time is largely determined by the RC time constant, where R is the internal pull-up resistor (10K) and C is the I/O signal trace capacitance. The FXLA2203 acts as a very low resistive short between the host and SIM card (during a LOW) until either of the port’s V thresholds are reached ...
