73S8009C-20IM/F

Overview

The 73S8009C-20IM/F is a smart card interface integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an operating supply voltage range of 2.7 V to 6.5 V and features a maximum operating temperature of +85°C with a minimum of -40°C. The device draws an operating supply current of 1.7 mA and is housed in a QFN-EP-20 package (QFN-20). It supports SMD/SMT mounting and includes moisture sensitivity protection.

Feature Summary

• Provides power management and smart card interface integration for system simplification
• Enables controller-controlled power on/off functionality via dedicated control pins
• Supports handshaking mechanisms for secure power state transitions

Applications

• Smart card readers
• Smart card writers
• Power management systems requiring smart card integration

Procurement Notes

Verify the specific package variant, as documentation references both QFN-EP-20 and 32-QFN configurations for similar part numbers. Confirm RoHS compliance status and ensure the supplier provides official datasheets matching the exact suffix. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when integrating smart card interfaces with power management capabilities in a compact surface-mount form factor. Ensure the application voltage falls within the 2.7 V to 6.5 V range and that thermal conditions remain between -40°C and +85°C. Consider the 1.7 mA supply current for power budget calculations.

Part Context

This IC belongs to the smart card interface series from Maxim Integrated, now part of Analog Devices. It is designed to simplify system integration by combining power management functions with smart card communication interfaces. The device is suitable for applications requiring robust power control alongside smart card connectivity.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully before substitution.
