Applications Information
SIM/Smart Card Interface
To provide 5V when interfacing with a 5V SIM/smart
card, 3V systems require a DC-DC converter. The
MAX1686H +5V regulating charge pump for SIM cards
provides 0V/3V/5V for full compatibility with SIM/smart
card specifications. Figure 4 shows the charge pump
for SIM card applications. Alternatively, the MAX619
generates a regulated 5V from input voltages as low as
2V.
SPI/QSPI/MICROWIRE Interface
The MAX1740/MAX1741 are also useful as 3V/5V level
shifters in SPI, QSPI, and MICROWIRE applications
(Figure 5). On the slave side, connect CLK to SCLK,
RST to
CS
, and IO to DOUT and DIN. The unidirectional
level shifters transfer chip select and clock signals to
the slave device(s), while the bidirectional level shifter
transfers data.
