VOLT - Smart USB Li-Po battery charger
The VOLT - Smart USB Li-Po BatteryCcharger makes it possible for the users to charge the battery of their devices over a USB connector. This intelligently designed Lithium-Polymer battery charger serves as a reliable power source for devices that are constantly hungry for more battery backup or USB power supply. The ability of the VOLT - Smart USB Li-Po battery charger to charge the battery over USB connector is attributable to its in-built MCP73832 linear charge power management circuitry. This power management controller limits the charge current based on die temperature during high power or high ambient conditions.
This thermal regulation optimizes the charge cycle time and thus makes this lithium-ion polymer battery charger a dependable and safe charger for user.
