PSC2725 - USB-Compliant Single-Cell Li-lon Switching Charger

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.

Features

  • for battery charging and system operation, including charging safety timer, and over-voltage/over-current protections. The STAT output reports the charging status and also can be used to notify the host when a fault occurs. The PSC2725 is available in a 24-pin, 4mm x 4mm x 0.55mm QFN package. U1 VBUS 1.8V CBUS 1uF CMID 22uF VBUS SW PMID BOOT PSC2725 VREF R2 R3 R4 10K 10K 10K OTG.

PSC2725 USB-Compliant Single-Cell Li-lon Switching Charger with USB-OTG Boost Regulator 1. 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. The I2C serial interface with charging and system settings makes the device a truly flexible solution. The device supports 3.5-6.0V input voltage sources, including standard USB host port and USB charging port with 6.1V over-voltage protection.
