Frequently Asked Questions
What input voltage and charge current does the LTC4162IUFD-LADM#PBF support for multi-cell Li-Ion packs?
The LTC4162IUFD-LADM#PBF handles input voltages up to 35 V and delivers a programmable charge current up to 3.2 A, making it suitable for 2-cell to 4-cell lithium-ion battery stacks used in portable industrial instruments and rugged handheld devices.
How does the integrated PowerPath feature benefit designs that must remain operational while charging?
PowerPath allows the system load to draw current directly from the input adapter while simultaneously charging the battery, providing zero hold-up time transitions. This ensures uninterrupted operation in medical monitors and data-logging equipment even when the battery is deeply discharged below 2.5 V per cell.
What real-time parameters can engineers read through the I2C telemetry interface?
Via I2C, the LTC4162IUFD-LADM#PBF reports input voltage, charge current, battery voltage, die temperature, and charge state registers. Engineers can use these 16-bit telemetry readings at up to 400 kHz I2C speed to implement fuel gauging, fault logging, and dynamic charge adjustment in firmware.
Which package does the LTC4162IUFD-LADM#PBF use, and how does it affect PCB layout for thermal management?
The device comes in a 28-pin QFN package with an exposed thermal pad, enabling efficient heat dissipation at full 3.2 A charge current. The compact footprint of approximately 4 mm x 5 mm allows tight integration alongside battery connectors and power inductors on space-constrained PCBs.
