What are the key features of LTC4162IUFD-L42M#PBF?
- 35 V input / 3.2 A charge current step-down topology supporting up to 4S lithium-ion battery packs
- Integrated PowerPath control for seamless transition between wall adapter and battery power without interruption
- I2C telemetry interface reporting voltage, current, temperature, and state-of-charge in real time
- Compact 28-pin QFN package enabling dense power management integration on small system boards
What is LTC4162IUFD-L42M#PBF used for?
The LTC4162IUFD-L42M#PBF is designed for industrial handheld instruments, portable medical devices, and IoT gateways that require robust multicell lithium-ion charging with real-time power telemetry. Its PowerPath feature ensures uninterrupted system operation when the charger input transitions between adapter and battery, critical in field data loggers and always-on edge computing nodes. The I2C telemetry capability also suits smart battery management systems in robotics and UAVs where state-of-charge reporting is needed for flight-time prediction and safe shutdown.

Frequently Asked Questions
What input voltage and maximum charge current does the LTC4162IUFD-L42M#PBF support?
The LTC4162IUFD-L42M#PBF accepts input voltages up to 35 V and delivers up to 3.2 A charge current, making it suitable for charging 2-cell to 4-cell lithium-ion battery packs in industrial handheld tools and portable instruments powered from standard 12 V or 24 V adapters.
How does the PowerPath feature of LTC4162IUFD-L42M#PBF benefit always-on system designs?
PowerPath allows the system load to draw current from the input adapter while simultaneously charging the battery, and automatically transitions to battery power within microseconds if the adapter is removed. This ensures zero system interruption in field data loggers and medical monitors that cannot tolerate even a brief power dropout.
What telemetry data can be read over I2C from LTC4162IUFD-L42M#PBF, and how does this help battery management?
Over I2C, the LTC4162IUFD-L42M#PBF reports battery voltage, charge current, input voltage, die temperature, and state-of-charge estimates. This real-time data enables the host MCU to implement adaptive charging profiles, thermal de-rating at elevated temperatures, and low-battery early warnings without external current-sense ICs.
When should a designer choose LTC4162IUFD-L42M#PBF over a simpler single-cell charger IC?
When the application requires 2S to 4S lithium-ion charging at currents above 1 A with simultaneous PowerPath and I2C monitoring — such as in a 3S drone battery pack or a 4S industrial scanner — the LTC4162IUFD-L42M#PBF replaces multiple discrete components, reducing BOM complexity and improving charger reliability at 3.2 A charge rates.
