BQ25300RTER from Texas Instruments, in a QFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VBUS | power_in | Charger input voltage in range 4.1V to 17V; reverse blocking MOSFET source connects here. |
| 2 | REGN | power_out | Low-side FET driver positive supply output from internal 5V LDO. |
| 3 | STAT | tri_state | Charge status indication open-drain output; pulled LOW during charging, open on completion, blinks at 1Hz for faults. |
| 4 | ICHG | input | Charge current program input; set charging current via ICHG = KICHG (40000) / RICHG; charging disabled if open or shorted to GND. |
| 5 | POL | input | EN pin polarity selection input; determines enable/disable logic for EN pin. |
| 6 | EN | input | Device enable/disable input; controls device power-up and charging based on POL pin setting. |
| 7 | TS | input | Battery temperature voltage input from NTC thermistor; charge suspends when temperature outside 0°C to 45°C window. |
| 8 | NC | unconnected | No connection; keep pin floating or grounded. |
| 9 | VSET | input | Charge voltage setting input; set final battery regulation voltage to 3.6V, 4.05V, 4.15V, or 4.2V via resistor divider. |
| 10 | BAT | input | Battery voltage sensing input; connect to battery positive terminal and inductor output node for voltage regulation feedback. |
| 11 | GND | power_in | Ground reference connected to thermal pad; single point connection recommended between power and analog ground. |
| 12 | GND | power_in | Ground reference connected to thermal pad; single point connection recommended between power and analog ground. |
| 13 | SW | tri_state | Switching node connected to output inductor; internally connected to source of high-side MOSFET and drain of low-side MOSFET. |
| 14 | SW | tri_state | Switching node connected to output inductor; internally connected to source of high-side MOSFET and drain of low-side MOSFET. |
| 15 | BTST | power_out | High-side FET driver bootstrap supply connected to bootstrap diode cathode; provides isolated gate drive voltage for high-side MOSFET. |
| 16 | PMID | tri_state | Power intermediate node connected to drain of reverse blocking MOSFET and drain of high-side MOSFET; actively switches between input and converter voltages. |
| 17 | Thermal Pad | power_in | Ground reference and thermal pad for die heat dissipation; must be soldered to PCB ground plane with vias for thermal conduction. |
