EMC1704-2-AP-TR

Product Overview

The EMC1704-2-AP-TR from Microchip Technology is a surface-mount integrated circuit for current sensing and temperature monitoring in power-management designs. The device is an I2C/SMBUS temperature monitor in a 16-QFN (4x4) package, with a 16-VQFN exposed-pad package. It operates from a 3 V to 24 V supply and draws 1.1 mA supply current. Its rated ambient operating range is -40°C to 85°C. The part supports board-level monitoring functions using a surface-mount package and digital interface.

Key Features

• Provides current sensing and temperature monitoring functions.
• Supports I2C/SMBUS digital communication.
• Operates from a 3 V to 24 V supply voltage.
• Has a 1.1 mA supply current.
• Rated for an ambient operating temperature range of -40°C to 85°C.
• Uses a surface-mount 16-VQFN exposed-pad package with a 16-QFN (4x4) footprint.

Applications

• Board-level current monitoring in power paths.
• Temperature monitoring of board-level thermal conditions.
• Power-management subsystems that report current and temperature data over I2C/SMBUS.

Design & Procurement Notes

For layout, the 16-QFN (4x4) package with an exposed pad requires surface-mount assembly and appropriate pad handling. The 3 V to 24 V supply range should be checked against the available power rail, and the 1.1 mA supply current should be included in power budget calculations. The -40°C to 85°C ambient operating range should be considered for the final board environment. The I2C/SMBUS interface should be integrated with a compatible host or controller, and the package footprint should be evaluated for mechanical and thermal layout requirements.
