LT2940CDD#TRPBF

Product Overview

Analog Devices Inc. LT2940CDD#TRPBF is a surface-mount current and power monitor IC in a 12-WFDFN exposed-pad package, with 12-DFN (3x3) device package dimensions. The device is intended for current and power monitoring within power-management systems. It operates from a 6V to 80V supply and draws 3.5mA supply current. Its operating temperature range is 0°C to 70°C. The package and surface-mount format support placement on printed circuit boards where monitoring circuitry is integrated with nearby power paths in the final assembly.

Key Features

• Current and power monitor IC for power-management systems.
• 12-WFDFN exposed-pad package, 12-DFN (3x3).
• 6V to 80V supply voltage range.
• 3.5mA supply current.
• 0°C to 70°C operating temperature range.
• Surface-mount mounting type.

Applications

• Load-current monitoring in power distribution paths.
• Power consumption measurement on supply rails.
• System current monitoring in power supply circuits.

Design & Procurement Notes

Designers should verify that the available supply voltage remains within the 6V to 80V range and that the 3.5mA supply current fits the system power budget. The 0°C to 70°C operating temperature range should be checked against the intended environment. The device uses a 12-WFDFN exposed-pad, 12-DFN (3x3) surface-mount package, so PCB pad layout and exposed-pad thermal handling should be planned during schematic and layout review for board-level integration. The 12-DFN (3x3) package footprint should also be checked against available PCB area. Confirm the exact manufacturer part number LT2940CDD#TRPBF during procurement. Because the part is a current and power monitor IC, selection should be based on the required monitoring function rather than assumptions about additional power-management capabilities.
