LTC4054ES5 in Linear Tech / ADI LT Series Family
The LTC4054ES5 is a sub-family of standalone linear battery chargers designed by Analog Devices (formerly Linear Technology) specifically for single-cell lithium-ion batteries. Known for its small SOT-23-5 footprint, it eliminates the need for an external sense resistor and blocking diode by integrating the power MOSFET. It utilizes a constant-current/constant-voltage algorithm with thermal regulation to maximize charging rates without the risk of overheating the PCB, making it a reliable choice for space-constrained power management designs.
Variants in This Sub-Family
| Part Number | Difference | Stock |
|---|---|---|
| LTC4054ES5-4.2#TRPBF (Analog Devices) | PBF | 2,519 |
Variants within the LTC4054ES5 family primarily differ in their packaging and procurement standards. While the core 4.2V charging specification remains consistent, options like the #PBF suffix denote lead-free compliance, while #TRMPBF and #TRPBF designate tape-and-reel quantities (mini versus standard). These variants ensure compatibility with different automated assembly volumes while maintaining the same thermal regulation and 800mA current capabilities.
