Frequently Asked Questions
What is the maximum charge current and input voltage supported by the LTC4162EUFD-FFSM#PBF?
The LTC4162EUFD-FFSM#PBF supports a maximum input voltage of 35 V and delivers up to 3.2 A of charge current, making it suitable for multi-cell LiFePO4 stacks used in portable industrial and medical equipment designs.
How does the PowerPath feature in the LTC4162EUFD-FFSM#PBF benefit always-on system designs?
The PowerPath control allows the system load to operate continuously from either the 35 V adapter or the LiFePO4 battery pack without brownout or interruption. It prioritizes the adapter when available, extending battery life and ensuring stable 3.2 A charge delivery.
Which communication interface does the LTC4162EUFD-FFSM#PBF use for telemetry, and what parameters can be read?
It uses an I2C interface to report real-time measurements including charge current, battery voltage, input voltage, and die temperature, enabling host microcontrollers to implement accurate state-of-charge algorithms and thermal protection for multi-cell LiFePO4 packs.
What package does the LTC4162EUFD-FFSM#PBF come in, and how does that affect thermal performance during 3.2 A charging?
The device is housed in a 28-pin QFN package with an exposed pad that conducts heat to the PCB ground plane, supporting sustained 3.2 A charging at up to 35 V input without requiring external heatsinks in typical applications with adequate copper pours.
