Frequently Asked Questions
What is the maximum input voltage and charge current supported by the LTC4162EUFD-L41#PBF?
The LTC4162EUFD-L41#PBF supports a maximum input voltage of 35V and delivers up to 3.2A of charge current, making it suitable for multi-cell lithium-ion battery packs in industrial and portable applications requiring high-power charging from wall adapters or solar panels.
How does the PowerPath feature in the LTC4162EUFD-L41#PBF benefit always-on system designs?
The PowerPath control of the LTC4162EUFD-L41#PBF allows the system load to be powered directly from the input source while simultaneously charging the battery, with automatic switchover to battery power when input is removed, ensuring zero downtime for critical loads in portable and backup-power systems operating from 9V to 35V inputs.
Which telemetry parameters can be monitored via the I2C interface of the LTC4162EUFD-L41#PBF?
Via its I2C interface, the LTC4162EUFD-L41#PBF provides real-time telemetry including battery voltage with 1.5mV resolution, charge current, input voltage, die temperature accurate to ±3°C, and charge state registers, enabling designers to implement precise battery health monitoring and fault diagnostics in smart energy systems.
What cell voltage does the LTC4162EUFD-L41#PBF target, and how does it relate to the 'L41' variant designation?
The 'L41' in LTC4162EUFD-L41#PBF indicates a 4.1V/cell charge termination voltage, which is slightly lower than the standard 4.2V/cell, extending cycle life for lithium-ion cells where longevity is prioritized over maximum capacity. This is especially useful in 2-cell or 3-cell packs where total pack voltage is 8.2V or 12.3V respectively.
