Battery charging controller offers multi-chemistry operation
Linear Technology has introduced the LTC4020, a high voltage power manager and multi-chemistry battery charger designed to transfer power from a variety of sources to a system power supply rail and a battery.
The device offers precision charge current regulation, ±0.5% charge voltage regulation and operates across a 4.5 to 55V input voltage range.
With an output voltage range up to 55V and three selectable termination algorithms, the LTC4020 accommodates an equally wide variety of battery stack voltages and chemistries.
It also contains a step up/step down dc/dc controller, enabling operation with battery voltages that are above, below or equal to the input voltage (VIN).
Typical applications include portable industrial and medical equipment, solar powered systems, military communications equipment, plus 12 to 24V embedded automotive systems.
