LTC4095EDC

Battery Chargers Overview

The LTC4095EDC is a standalone linear Li-Ion/Li-Polymer battery charger IC designed for USB-powered applications. It supports a single-cell battery configuration with a regulated output voltage of 4.2V and delivers a programmable charge current up to 950mA, set by a single external resistor. The device operates within an input voltage range of 4.3V to 5.5V. It is housed in an 8-pin DFN EP package.

Battery Chargers Feature Summary

• Standalone operation without requiring microcontroller or complex interface logic
• Programmable charge current via a single external resistor
• Integrated thermal regulation to manage power dissipation during charging

Battery Chargers Applications

• Portable consumer electronics powered by USB
• Single-cell lithium-ion battery management systems
• Single-cell lithium-polymer battery charging circuits

Battery Chargers Procurement Notes

Verify the specific suffix (e.g., TRPBF, TRMPBF, PBF) against the required packaging format and RoHS compliance status. Confirm that the 8-pin DFN EP footprint matches the target PCB layout. Ensure the selected variant aligns with the intended production volume and supply chain requirements.

Battery Chargers Selection Notes

Select this component when designing compact chargers limited to standard USB input voltages. It is suitable for applications prioritizing minimal bill-of-materials count and simplified circuit topology over high-efficiency switching architectures. Verify that the maximum 950mA current capability meets the target battery's charging specifications.

Battery Chargers Part Context

This part belongs to the LTC4095 series of linear battery chargers manufactured by Analog Devices Inc. It is functionally similar to other standalone linear chargers but is distinguished by its specific 8-pin DFN EP package and 950mA current rating. It serves as a direct solution for simple, cost-effective USB charging needs.

Battery Chargers Replacement Considerations

Direct pin-to-pin replacements are not explicitly confirmed in public documentation. Evaluate alternative Linear Technology/Analog Devices chargers such as the LTC4059A or LTC4099 only if system constraints allow for different packages or control interfaces.
