Part Number: NCN4555
Function: 1.8V / 3V SIM Card Power Supply and Level Shifter
Package: QFN 16 Pin Type
Manufacturer: ON Semiconductor
The NCN4555 is a level shifter analog circuit designed to translate the voltages between a SIM Card and an external microcontroller or MPU.
A built−in LDO−type DC−DC converter makes the NCN4555 useable to drive 1.8 V and 3.0 V SIM card.
1. Supports 1.8 V or 3.0 V Operating SIM Card
2. The LDO is able to Supply More than 50 mA under 1.8 V and 3.0 V
3. Built−in Pullup Resistor for I/O Pin in Both Directions
4. Supports up to More than 5 MHz Clock
1. Identification Module
2. Smart Card Readers
3. Wireless PC Cards
