PSC5415E

PSC5415E USB-Compliant Single-Cell Li-lon Switching Charger with USB-OTG Boost Regulator Description PSC5415E is a switch-mode charging IC with maximum 1.75A current for lithium battery and lithium polymer battery. The PSC5415E has 5V, 700mA OTG function, and I2C function. The charging parameter such as charging current, full charging voltage and input current can be precisely configured by I2C function. The package type is WLCSP (1.901mmx1.501mm) with 20 pins. The PSC5415E is designed with standard four-stage charging process: active, pre-charging, constant current, constant voltage and perfect protection mechanism for over current, over voltage, under voltage and over temperature. It is integrated with synchronous PW M control, high power MOSFET, and high voltage OVP circuits. The PSC5415E has high charging efficiency (94%), low internal resistance (45mΩ), and high DC withstand voltage (29V).

Bypass with a minimum of 4.7μF, 10V capacitor to PGND. 2 Status. Open-drain output indicating charge status. The IC pulls this pin LOW when charge is in process. Power Ground. Power return for gate drive and power transistors. The connection from this pin to the bottom of CMID should be as short as possible. On-The-Go. Enables boost regulator in conjunction with OTG_EN and OTG_PL bits Current-Sense Input. Connect to the sense resistor in series with the battery. The IC uses this node to sense current into the battery. Bypass this pin with a 0.1μF capacitor to PGND. Charge Disable. If this pin is “1”, charging is disabled. When LOW, charging is controlled by I2C registers. Bias voltage. Connect to a 4.7uF capacitor to PGND. The output voltage is PMID, which is limited to 6.5V. Any resistor loading to VREF is NOT recommended. Battery Voltage. Connect to the positive (+) terminal of the battery pack. Bypass with a 0.1μF capacitor to PGND if the battery is connected through long leads. 3 、 www.prisemi.com PSC5415E USB-Compliant Single-Cell Li-lon Switching Charger with USB-OTG Boost Regulator Product dimension E BALL A1 INDEX AREA F A B 1.20 0.03 C Ø0.15 Cu Pad A1 2X D 1.60 0.40 Ø0.18 Solder Ball Size 0.40 0.03 C 2X TOP VIEW RECOMMENDED LAND PATTERN (NSMD TYPE) 0.06 C 0.05 C 0.365±0.018 0.140±0.012 E 0.535 0.475 C SEATING PLANE D SIDE VIEWS NOTES: 0.005 M C A B B.DIMENSIONS ARE IN MILLIMETERS. ᶲ 1.20 0.40 C.DIMENSIONS AND TOLERANCE E PER ASMER14.5M,1994.
