WLCSP-20 Pin Assignments Pin Definitions Pin # Name Part # Description A1, A2 VBUS ALL Charger Input Voltage and USB-OTG output voltage. Bypass with a 1 F capacitor to PGND. A3 NC ALL No Connect . No external connection is made between this pin and the IC’s internal circuitry. A4 SCL ALL I 2C Interface Serial Clock. This pin should not be left floating. B1-B3 PMID ALL Power Input Voltage . Power input to the charger regulator, bypass point for the input current sense, and high-voltage input switch. Bypass with a minimum of 4.7 F, 6.3V capacitor to PGND. B4 SDA ALL I 2C Interface Serial Data. This pin should not be left floating. C1-C3 SW ALL Switching Node . Connect to output inductor. C4 STAT ALL Status . Open-drain output indicating charge status. The IC pulls this pin LOW when charge is in process. D1-D3 PGND ALL 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. D4 OTG ALL On-The-Go . Enables boost regulator in conjunction with OTG_EN and OTG_PL bits (see Table 16) . On VBUS Power-On Reset (POR), this pin sets the input current limit for t15MIN charging. E1 CSIN ALL 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 0.1 F capacitor to PGND. E2 AUXPWR FAN5400, FAN5401, FAN5402 Auxiliary Power . Connect to the battery pack to provide IC power during High-Impedance Mode. Bypass with a 1 F capacitor to PGND. E2 DISABLE FAN5403, FAN5404, FAN5405 Charge Disable . If this pin is HIGH, charging is disabled. When LOW, charging is controlled by the I 2C registers. When this pin is HIGH, the 15-minute timer is reset. This pin does not affect the 32-second timer. E3 VREG ALL Regulator Output . Connect to a 1 F capacitor to PGND. This pin can supply up to 2mA of DC load current. For FAN5400-FAN5402, the output voltage is PMID, which is limited to 6.5V. For FAN5403-FAN5405, the output voltage is regulated to 1.8V. E4 VBAT ALL Battery Voltage . Connect to the positive (+) terminal of the battery pack. Bypass with a 0.1 F capacitor to PGND if the battery is connected through long leads. |
