TDA8037T/C1S

Smart Card Interface 10MHz 3.3V 0.1W1/10W Tube 28Pin SO

Overview

The TDA8037 is the cost efficient successor of the established integrated contact smart card reader IC TDA8035. It offers a high level of security for the card performing current limitation, short circuit detection, ESD protection as well as supply supervision. Operating in 3 V supply domain, the current consumption during the shutdown mode of the contact reader is very low. It 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:

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

* Current spikes of 40 nA up to 20 MHz, with controlled rise and fall times, filtered overload detection 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, VDDhost, VREG and VDD dropping

* 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 with SO28 package only
