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 VDD. Dependent on the SIM card used, a control signal coming from the SIM card controller is applied on 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. The SIM supply is operating provided SIMPWR = 1 and VDD is sufficient (> 2.7 V). Under this condition, SIMVCC 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 TIs thin shrink small-outline package (PW). By Texas Instruments
