LTC1955IUH#TRPBF Description

Short technical summary and product information.

The LTC1955IUH#TRPBF is a dual smart card interface IC manufactured by LT, designed to provide power management and control functions for two smart cards, S.A.M. cards, or a combination thereof. It is compatible with ISO7816-3 and EMV standards.

 

This device features a buck/boost charge pump capable of generating independent 5V, 3V, or 1.8V outputs for each smart card, supporting Classes A, B, and C. It includes supervisory functions to prevent smart card faults and automatic shutdown on electrical faults. The typical operating current is 250µA, with ultralow shutdown current. ESD protection on smart card pins exceeds 10kV.

 

The LTC1955IUH#TRPBF is housed in a compact 32-lead 5mm x 5mm QFN package. Its control and status serial port can be daisy-chained for multicard applications. This IC is suitable for applications such as handheld payment terminals, pay telephones, and ATM machines.
