PSC2725 Overview
Description
PSC2725 combines a highly integrated switch-mode charger, to minimize single-cell Lithium-ion (Li-ion) charging time from a USB power source, and a boost regulator to power a USB peripheral from the battery. Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charge time and extends battery life during discharging phase.
Key Features
- the system keeps operating even when the battery is completely depleted or removed
- This supplement mode operation keeps the input source from getting overloaded
- The device initiates and completes a charging cycle when host control is not available
- It automatically charges the battery in three phases: pre-conditioning, constant current, and constant voltage
- In the end, the charger automatically terminates when the charge current is below a preset limit in the constant voltage phase
