LTC1734LES6-4.2#TRPBF

Battery Chargers Overview

The LTC1734LES6-4.2#TRPBF is a lithium-ion linear battery charger IC manufactured by Analog Devices Inc., designed for single-cell applications with a fixed 4.2V output voltage. It operates within an input voltage range of 4.7V to 7V and supports a maximum programmable charging current of 180mA. The device features overcurrent and overtemperature fault protection mechanisms to ensure safe operation. It is housed in a TSOT-23-6 surface-mount package and is rated for an operating temperature range from -40°C to +85°C.

Battery Chargers Feature Summary

• Supports multi-chemistry battery types including Lithium-Ion and Lithium Polymer
• Integrates overcurrent and overtemperature fault protection
• Features programmable constant-current charging capability

Battery Chargers Applications

• Single-cell lithium-ion battery management systems
• Portable electronic devices requiring compact power solutions
• Battery-powered equipment utilizing small form-factor ICs

Battery Chargers Procurement Notes

Verify the specific suffix #TRPBF against official manufacturer documentation to confirm tape-and-reel packaging requirements. Ensure compatibility with the intended PCB footprint for the TSOT-23-6 package. Cross-reference the part number with authorized distributors to confirm current availability status, as supply conditions may vary. Confirm that the 180mA current rating meets the specific application needs rather than assuming higher capabilities associated with other variants in the series.

Battery Chargers Selection Notes

Select this component when a low-cost, single-cell linear charger is required for space-constrained designs. The TSOT-23-6 package offers a compact solution compared to larger alternatives. Consider the 180mA maximum current limit; if higher charging speeds are necessary, evaluate the LTC1734ES6 variant which supports up to 700mA. Ensure the input voltage source remains within the specified 4.7V to 7V range for proper regulation.

Battery Chargers Part Context

This part belongs to the LTC1734 family of battery chargers from Analog Devices. It shares functional similarities with the LTC1734ES6-4.2 but differs in maximum current capacity. The 'L' prefix typically denotes specific performance characteristics or cost-tier variations within the product line. It is distinct from switching regulators like the LTC3803 or buck converters like the LTC3130 found in related catalogs.

Battery Chargers Replacement Considerations

The LTC1734ES6-4.2#TRPBF serves as a direct functional substitute with higher current capability (700mA vs 180mA). The LTC1734LES6-4.1#TRPBF is compatible if a 4.1V output is acceptable. Verify pinout and thermal performance when substituting between ES and LE series parts.
