PSC2945 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. The I2C serial interface with charging and system settings makes the device a truly flexible solution.
The device supports 3.5-12V input voltage sources, including standard USB host port and USB charging port with programmable over-voltage protection. The device also supports USB On-the-Go operation by providing on the VBUS with an accurate current limit.
