BQ24315DSGR from Texas Instruments, in a WSON-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input power supply from external adapter; supports input voltage range 3.3V to 30V with maximum input current 1.5A; must be bypassed to VSS with 1µF minimum ceramic capacitor. |
| 2 | VSS | power_in | Ground terminal and primary ground connection point for the device; internally connected to exposed thermal pad. |
| 3 | NC | unconnected | No connection pin for internal test purposes; should not be externally connected during normal operation. |
| 4 | FAULT | output | Open-drain active-low status output indicating fault condition from input overvoltage, input overcurrent, battery overvoltage, or thermal shutdown; maximum output sink current 15mA; high impedance during normal operation. |
| 5 | CE | input | Chip enable active-low input; high voltage (>1.4V) disables IC and turns off internal FET; low voltage (<0.4V) enables normal operation; internally pulled down; can be left floating. |
| 6 | VBAT | power_in | Battery voltage sense input for battery overvoltage protection with 4.35V threshold; input bias current approximately 10nA at 4.4V; connect to battery positive terminal through 100kΩ to 470kΩ resistor. |
| 7 | ILIM | bidirectional | Input overcurrent threshold programming pin; connect resistor from ILIM to VSS to set OCP threshold per equation IOCP = 25kΩ ÷ R(ILIM) where IOCP is in amperes and R is in kilohms; programmable threshold range 300mA to 1500mA. |
| 8 | OUT | power_out | Regulated output power to charging system; output voltage 5.3V to 5.7V (nominal 5.5V for bq24315) when input voltage between 5.5V and overvoltage threshold; maximum output current 1.5A; must be bypassed to VSS with 1µF minimum ceramic capacitor. |
| 9 | Thermal Pad | power_in | Exposed thermal pad electrically connected to VSS; must be soldered to PCB ground plane for thermal performance; do not use as primary ground input-VSS pin must be connected to ground. |
