LT1571EGN-5#TRPBF

Battery Chargers Overview

The LT1571EGN-5#TRPBF is a constant-current/constant-voltage battery charger IC from Analog Devices, designed for lithium-ion and lithium-polymer cells. It operates with a maximum input voltage of 27 V and features a preset output voltage of 4.1 V. The device is housed in a 16-lead SSOP package and supports surface-mount installation. It includes a termination flag for charging status indication and functions within an operating temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Implements constant-current and constant-voltage charging profiles for single-cell batteries
• Includes a dedicated termination flag output to indicate charge completion
• Supports operation with lithium-ion and lithium-polymer battery chemistries

Battery Chargers Applications

• Portable electronic devices requiring Li-Ion battery management
• Lithium-polymer cell charging systems
• Battery-powered equipment with limited space constraints

Battery Chargers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified suppliers. Confirm the presence of the #TRPBF suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Request original manufacturer documentation to validate part integrity before integration into production designs.

Battery Chargers Selection Notes

Select this component when a fixed 4.1 V output is required for standard lithium-ion applications. Ensure the system input voltage does not exceed 27 V. Consider the SSOP-16 package dimensions for PCB layout compatibility. Verify thermal requirements against the specified -40°C to +85°C operating range for the intended environment.

Battery Chargers Part Context

This part belongs to the LT1571 series of battery chargers manufactured by Analog Devices. It is categorized under Power Management ICs (PMIC) specifically for charge management. The device is distinct from switching regulators like the LTC3831, focusing solely on linear battery charging control rather than DC-DC conversion.

Battery Chargers Replacement Considerations

Consult official Analog Devices documentation for verified cross-references. No direct substitute part numbers are confirmed in the provided source material. Evaluate alternative Linear Technology battery chargers only if they match the 4.1 V preset and SSOP-16 package specifications.
