Frequently Asked Questions
What is the maximum input voltage and charge current of LTC4162EUFD-LADM#PBF, and how are they set?
The LTC4162EUFD-LADM#PBF accepts up to 35 V input and delivers up to 3.2 A charge current; both the charge voltage and input current limit are digitally programmable via the I2C interface, enabling on-the-fly adaptation to USB PD, wall adapters, or solar panel sources.
How does the PowerPath feature in LTC4162EUFD-LADM#PBF benefit an always-on industrial device?
PowerPath automatically prioritizes input power to the system load while simultaneously charging the battery; when the adapter is disconnected, power seamlessly transfers to the battery within microseconds, eliminating reset glitches in data-logging or measurement systems running 24/7.
What telemetry parameters does LTC4162EUFD-LADM#PBF report over I2C for a battery management system?
It reports battery voltage (VBAT), charge/discharge current (IBAT) with ±1% accuracy, input voltage (VIN), system voltage, die temperature in °C, and charger status registers, providing all data needed for coulomb-counting fuel-gauge algorithms without external current-sense ICs.
For a 2-cell Li-ion pack design, what is the typical charger efficiency of LTC4162EUFD-LADM#PBF compared to a linear charger?
Using its integrated step-down switching topology, LTC4162EUFD-LADM#PBF achieves up to 90% conversion efficiency when charging a 2-cell pack from a 12 V adapter, compared to under 70% for a linear charger, significantly reducing heat dissipation and enabling smaller thermal designs.
