LT3650EMSE-4.1#TRPBF

Battery Chargers Overview

The LT3650EMSE-4.1#TRPBF is a monolithic switching battery charger designed for single-cell lithium-ion or lithium-polymer batteries, featuring an integrated high-voltage MOSFET and power path management. It supports a maximum input voltage of 32V and delivers a programmable constant current up to 2A. The device terminates charging at a fixed 4.1V output voltage. It operates within a temperature range of -40°C to 85°C and is housed in a 12-lead MSOP package with an exposed thermal pad.

Battery Chargers Feature Summary

• Integrates a high-voltage N-channel MOSFET switch to eliminate external blocking diodes
• Manages system power distribution through automatic source prioritization between adapter and battery
• Includes thermal regulation that dynamically reduces charge current to limit die temperature
• Provides safety timer programming to terminate charging if no battery is detected

Battery Chargers Applications

• Portable medical devices requiring compact power solutions
• Handheld instrumentation and measurement tools
• Industrial handheld controllers and scanners
• Consumer electronics utilizing single-cell Li-Ion or Li-Pol batteries

Battery Chargers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm the exact termination voltage and package variant. Ensure the ordering part number matches the required tape and reel quantity specifications. Cross-reference the manufacturer's latest datasheet for any recent design changes or environmental compliance updates prior to final procurement.

Battery Chargers Selection Notes

Select this component when designing systems powered by a single-cell lithium battery where space constraints prohibit external switching regulators. It is suitable for applications requiring precise charge termination voltages and robust thermal protection. Consider the 32V input tolerance for environments with noisy power lines or automotive-grade requirements.

Battery Chargers Part Context

This part belongs to the LT3650 family of high-voltage linear chargers from Analog Devices. The family includes variants with different fixed termination voltages (e.g., 4.2V, 8.4V) to accommodate various battery configurations. The EMSE suffix indicates the specific MSOP package type used for surface-mount assembly.

Battery Chargers Replacement Considerations

LT3650EMSE-4.2#TRPBF: Offers identical functionality but with a 4.2V termination voltage instead of 4.1V.
