Low-Power, Dual SIM Card Analog Switch
FSA2567
Description The FSA2567 is a bi−directional, low−power, dual double−pole,
double−throw (4PDT) analog switch targeted at dual SIM card multiplexing. It is optimized for switching the WLAN−SIM data and control signals and dedicates one channel as a supply−source switch.
The FSA2567 is compatible with the requirements of SIM cards and features a low on capacitance (CON) of 10 pF to ensure high−speed data transfer. The VSIM switch path has a low RON characteristic to ensure minimal voltage drop in the dual SIM card supply paths.
The FSA2567 contains special circuitry that minimizes current consumption when the control voltage applied to the SEL pin is lower than the supply voltage (VCC).
