Product Details

The LTC4162-L is an advanced monolithic synchronous step-down switching battery charger and PowerPath™ manager that seamlessly manages power distribution between input sources such as wall adapters, backplanes, solar panels, etc., and a rechargeable Lithium-Ion/Polymer battery.

A high resolution measurement system provides extensive telemetry information for circuit voltages, currents, battery resistance and temperature which can all be read back over the I2C port. The I2C port can also be used to configure many charging parameters including charging voltages and currents, termination algorithms and numerous system status alerts.

The LTC4162-L can charge Lithium-Ion cell stacks from 1 cell to 8 cells with as much as 3.2A of charge current.

The power path topology decouples the output voltage from the battery allowing a portable product to start up instantly under very low battery voltage conditions.

The LTC4162-L is available in a thermally enhanced 28-pin 4mm × 5mm × 0.75mm QFN surface mount package.
