Overview

The TDA8035 is the cost efficient successor of the established integrated contact smart card reader IC TDA8024. It offers a high level of security for the card by performing current limitation, short-circuit detection, ESD protection as well as supply supervision. The current consumption during the standby mode of the contact reader is very low as it operates in the 3 V supply domain. The TDA8035 is therefore the ideal component for a power efficient contact reader.

## Features

### Protection of the contact smart card

* Thermal and short-circuit protection on all card contacts

* VCC regulation:

* 5 V, 3 V, 1.8 V ± 5 % on 2 × 220 nF multilayer ceramic capacitors with low ESR

* current spikes of 40 nA/s VCC = 5 V and 3 V or 15 nA/s VCC = 1.8 V up to 20 MHz, with controlled rise and fall times, filtered overload detection is approximately 120 mA

* Automatic activation and deactivation sequences initiated by software or by hardware in the event of a short-circuit, card take-off, overheating, falling VREG VDDINTF,VDDP

* Enhanced card-side ElectroStatic Discharge ESD protection of > 8 kV

* Supply supervisor for killing spikes during power on and off:

* threshold internally fixed

* externally by a resistor bridge
