description  
The TPS9125 SIM supply and level shifter integrates a programmable 3-V or 5-V SIM supply, conformable to  
the (GSM) test specification 11.10, together with either a 3-V or 5-V level shifter, conformable to the GSM  
specification 11.11 and 11.12.  
A charge pump, utilizing two external capacitors, is configured as voltage doubler to generate a 5-V supply rail  
from V . Dependent on the SIM card used, a control signal coming from the SIM card controller is applied on  
DD  
the MODE terminal to switch between a 3-V or 5-V supply on the SIMVCC output terminal.  
A 3-V/5-V bidirectional level shifter translates the 3-V compatible logic signal on DATA terminal into a 5-V  
compatible logic signal SIMDATA terminal, and vice versa. RST and CLK are unidirectional level shifters,  
providing a 5-V SIMRST and SIMCLK signal from the microcontroller to the SIM card.  
TheSIMsupplyisoperatingprovidedSIMPWR=1andV issufficient(>2.7V). Underthiscondition, SIMVCC  
DD  
voltage is generated by the SIM supply charge pump.  
A RESET terminal is provided for security reasons to switch off the SIM supply and interface if the SIM card is  
disconnected or removed by accident.  
The TSP9125 is packaged in TI’s thin shrink small-outline package (PW).
