Frequently Asked Questions
What is the maximum input voltage and charge current of the LTC4162IUFD-SAD#PBF?
The LTC4162IUFD-SAD#PBF accepts up to 35 V on its input and delivers a maximum charge current of 3.2 A, making it suitable for charging 2-cell to 4-cell Li-ion battery packs from solar panels, vehicle adapters, or 24 V industrial supplies.
How does the PowerPath feature benefit portable instrument designs using LTC4162IUFD-SAD#PBF?
PowerPath allows the system load to draw current directly from the 35 V input rail while simultaneously charging the Li-ion battery at up to 3.2 A. This prevents system shutdown during charging and enables instant-on operation even with a deeply discharged battery, critical for medical and industrial handheld devices.
Which parameters does the I2C telemetry interface expose on the LTC4162IUFD-SAD#PBF?
Via I2C, the LTC4162IUFD-SAD#PBF reports real-time battery voltage, charge current, input voltage, die temperature, and charge state register values. This 16-bit resolution telemetry enables accurate state-of-charge algorithms and thermal management in host firmware without external sensing ICs.
In what package is LTC4162IUFD-SAD#PBF available and how does it affect thermal management?
The LTC4162IUFD-SAD#PBF is housed in a 28-pin QFN package with an exposed pad for direct PCB thermal dissipation. At 3.2 A charge current, the exposed pad allows heat transfer to copper pours, keeping junction temperature within safe limits in compact 4-layer PCB designs.
