Frequently Asked Questions
How does the LTC4162EUFD-LAD#PBF handle power delivery to the load during active charging?
The LTC4162EUFD-LAD#PBF uses an integrated PowerPath topology that prioritizes powering the system load directly from the input supply at up to 35 V while simultaneously charging the battery at up to 3.2 A. If the input is removed, the device instantly switches to battery power with no interruption to the load, making it suitable for always-on industrial and medical instruments.
What real-time parameters can a host MCU read via the I2C interface of the LTC4162?
Via the I2C interface, a host MCU can read battery voltage with 1.653 mV/LSB resolution, charge current, input voltage, die temperature in 0.0215 °C/LSB steps, and system output voltage. These telemetry values enable firmware to compute battery state-of-charge, log energy throughput, and trigger thermal protection routines before damage occurs.
Which multi-cell battery configurations does the LTC4162EUFD-LAD variant support?
The LTC4162EUFD-LAD variant is factory-configured for lithium-ion chemistry with a charge voltage preset supporting 1 to 4 series cells, corresponding to full-charge voltages from approximately 4.2 V to 16.8 V. The adjustable threshold feature allows fine-tuning of termination and recharge voltages to match specific lithium polymer or LiFePO4 cell chemistries within the 35 V input limit.
What PCB thermal considerations apply when operating the LTC4162 at 3.2 A continuous charge current?
At 3.2 A charge current with a 10 V input and 8.4 V output (2-cell configuration), the step-down converter dissipates approximately 0.7 W in the 28-pin QFN package. The exposed thermal pad must connect to at least 400 mm² of 1 oz copper pour on the PCB to keep junction temperature below 125 °C in a 25 °C ambient, following Analog Devices layout recommendations.
When is the LTC4162EUFD-LAD#PBF a better procurement choice than discrete charger plus PowerPath solutions?
The LTC4162EUFD-LAD#PBF integrates a step-down charger, PowerPath switch, and I2C telemetry ADC in a single 28-pin QFN, replacing circuits that typically require 3 to 5 discrete ICs plus passive components. For system designs where BOM cost reduction and PCB space savings below 100 mm² are critical—such as portable medical devices or industrial PDAs—this integration delivers faster time-to-market and simpler regulatory qualification.
