Overview:
The LTC4054ES5-4.2#TRPBF is a compact and highly integrated charger IC targeted for portable devices that use single-cell lithium-ion/polymer batteries. It offers a reliable and efficient charging solution while providing a simple and straightforward design for the end-user.
Key Features:
1. Standalone Operation: The LTC4054ES5-4.2#TRPBF is a fully autonomous charger, making it suitable for applications requiring low external component count or tight space constraints.
2. Wide Input Voltage Range: It can accept input voltages up to 6V, enabling the charger to operate from a variety of power sources, including USB ports, wall adapters, and other power supplies.
3. Constant-Current/Constant-Voltage Charging: The IC charges the lithium-ion/polymer battery using a two-stage process. It starts with a constant current charging mode to quickly charge the battery until a certain voltage threshold is reached. Then, it transitions into a constant voltage mode to deliver a precise and safe charge, avoiding overcharging and damage to the battery
