LTC4361CDC-2

Power Management - Specialized Overview

The LTC4361CDC-2 is an overvoltage and overcurrent protection controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5V to 80V DC and draws a typical supply current of 220µA. The device is housed in an 8-WFDFN (2x2) package with exposed pad, suitable for surface mount installation. It supports an operating temperature range from -40°C to +85°C. This component functions as a board-mount surge protector designed to safeguard downstream circuitry against electrical faults.

• Provides integrated overvoltage and overcurrent protection control
• Supports wide input voltage ranges up to 80V DC
• Designed for compact surface-mount applications

Power Management - Specialized Applications

• Handheld computers
• Mobile devices
• USB port protection

Power Management - Specialized Procurement Notes

Verify the specific suffix 'CDC-2' against official Analog Devices documentation to confirm pinout and threshold configurations. Ensure compatibility with the required thermal dissipation capabilities of the 8-WFDFN package. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring precise overvoltage and overcurrent monitoring for portable electronics. The low quiescent current makes it suitable for battery-powered applications. Ensure the PCB layout accommodates the 2x2mm footprint and provides adequate thermal relief for the exposed pad to maintain reliability under operational stress.

Power Management - Specialized Part Context

This part belongs to the LTC4361 series of surge stoppers and protection controllers. It is distinct from the LTC4364 series, which integrates an ideal diode function. The LTC4361 family focuses on external switch control or direct protection without internal pass elements, offering flexibility for various system architectures requiring robust fault management.

Power Management - Specialized Replacement Considerations

Official substitutes include other variants within the LTC4361 family, such as LTC4361IDC-2 or LTC4361ITS8-2, depending on the required package type and specific threshold settings. Verify functional equivalence regarding voltage thresholds and control logic before substitution.
