LTC2952CF

Power Supply Controllers, Monitors Overview

The LTC2952CF is a specialized power management IC integrating pushbutton on/off control, an ideal diode controller for power path management, and system voltage supervision. It operates within a supply voltage range of 3V to 25V and features a TSSOP-20 package. The device monitors input sources to manage automatic OR-ing between a wall adapter and a battery, while providing precise control over DC/DC converter enable signals via a single pushbutton interface.

Power Supply Controllers, Monitors Feature Summary

• Integrates pushbutton on/off controller with ideal diode power path management
• Provides accurate system voltage supervision and monitoring capabilities
• Enables automatic power OR-ing between primary and backup power sources

Power Supply Controllers, Monitors Applications

• Systems requiring automatic power OR-ing between wall adapters and batteries
• Pushbutton-controlled DC/DC converter enable circuits
• Portable devices needing integrated power path and supervisor functions

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix CF against official Analog Devices documentation to confirm temperature grade and packaging configuration. Confirm current availability status as distribution channels may indicate limited stock or discontinuation. Ensure the ordering part number matches the exact electrical specifications required for your design before finalizing procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component when a single IC solution is needed for both power path management and user interface control. It is suitable for designs requiring seamless switching between AC adapter and battery power without external logic. Verify that the TSSOP-20 package fits the board layout constraints and that the 3V to 25V input range covers all expected operating conditions.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2952 family from Analog Devices, designed for compact power management applications. It consolidates multiple discrete functions into one chip, reducing bill of materials count. The device is intended for use in portable electronics where space efficiency and reliable power source switching are critical design requirements.

Power Supply Controllers, Monitors Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the LTC2954, if interrupt capabilities are required instead of basic supervision. Verify functional equivalence regarding threshold voltages and output drive strengths before substitution.
