Overview
The PSC5425E 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. The charging parameters and operating modes are programmable through an I²C interface. The charger and boost regulator circuits switch at select-able frequency to lower the EMI and minimize the size of external passive components. The PSC5425E provides battery charging in three phases: conditioning, constant current, and constant voltage. To ensure USB compliance and minimize charging time, the input current is limited to the value set through the I²C host. Charge termination current is programmable through the I²C host. The integrated circuit (IC) automatically restarts the charge cycle when the battery falls below an internal threshold. If the input source is removed, the IC enters a high-impedance mode with leakage from the battery to the input prevented. Charge status is reported back to the host through the I²C port. The PSC5425E can operate as a boost regulator on command from the system. The boost regulator includes a soft-start that limits inrush current from the battery. The PSC5425E is available in a 20-bump, 0.4mm pitch WLCSP package.
