Frequently Asked Questions
What input voltage and maximum charge current does the LTC4162EUFD-SAD#PBF support?
The LTC4162EUFD-SAD#PBF accepts input voltages up to 35 V and delivers a maximum charge current of 3.2 A into multi-cell Li-Ion battery packs. This combination suits charging from 12 V to 24 V industrial adapters while managing 2-cell or 3-cell battery stacks common in portable instruments and field devices.
How does the PowerPath feature of the LTC4162EUFD-SAD#PBF benefit always-on system designs?
The PowerPath architecture in the LTC4162EUFD-SAD#PBF allows the system load to draw power directly from the input rail while simultaneously charging the battery at up to 3.2 A. This prevents voltage droop on the system rail during heavy charging and ensures devices like industrial data loggers continue operating without interruption even when the battery is nearly depleted.
What telemetry data can a host processor read from the LTC4162EUFD-SAD#PBF over I2C?
Via its I2C interface, the LTC4162EUFD-SAD#PBF provides real-time telemetry including input voltage, battery voltage, charge current, die temperature, and charge state register data. This 1-channel telemetry readout allows firmware to implement adaptive charging algorithms, thermal derating above 85°C, and accurate state-of-charge estimation without additional external measurement circuits.
In which portable or industrial product categories is the LTC4162EUFD-SAD#PBF most commonly used?
The LTC4162EUFD-SAD#PBF is well suited for portable industrial analyzers, medical monitoring equipment, and ruggedized handheld devices powered by 2- to 4-cell Li-Ion packs. Its 35 V input tolerance accommodates wide-range DC adapters and vehicle power inputs, while the 28-pin QFN package fits within compact PCB areas typical of handheld products requiring 3.2 A charging capability.
