No.09056EAT02

●Overview

BD8904F, BD8904FV, BD8905F, BD8906F, BD8906FV and BD8907F are an interface IC for a 3V or 5V smart card.

It works as a bidirectional signal buffer between a smart card and a controller. Also, it supplies 3V or 5V power to a smart

card. With electrostatic breakdown voltage of more than HBM: ±6000V, it protects the card contact pins.

●Features

1) 3 half duplex bidirectional buffers

2) Protection against short-circuit for all the card contact pins

3) Card power source (VREG) of 3V or 5V

4) Overcurrent protection for card power source

5) Built-in thermal shutdown circuit

6) Built-in supply voltage detector

7) Automatic start-up/shutdown sequence function for card contact pin

Start-up sequence: driven by a signal from controller (CMDVCCB↓)

Shutdown sequence: driven by a signal from controller (CMDVCCB↑) and fault detection (card removal,

short circuit of card power, IC overheat detection, VDD or VDDP drop)

8) Card contact pin ESD voltage ≧ ±6000V

9) 2MHz - 26MHz integrated crystal oscillator

10) Programmable for clock division of output signal by 1, 1/2, 1/4, and 1/8

11) RST output control by RSTIN input signal (positive output)

12) One multiplexed card status output by OFFB signal
