AIC1519N-0GS8TR from AIC Analog Integrations, in a SOP-8. 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 | CTLA | input | Enable / control input for channel A high-side switch. Active-LOW on the AIC1519N-0 variant (Logic 0 = switch ON). Logic thresholds: VIL ≤ 0.8 V, VIH ≥ 2.4 V; input current ~0.01 µA; input capacitance ~1 pF; absolute max -0.3 V to +7 V. |
| 2 | FLGA | output | Open-drain fault flag output for channel A. Pulled LOW when channel A is in over-current limiting, thermal shutdown, or UVLO. Requires an external pull-up (typ 10 kΩ to Vcc). Absolute max VFLG = 7 V, IFLG = 50 mA; on-resistance ~15 Ω at VIN = 5 V, IL = 10 mA. |
| 3 | FLGB | output | Open-drain fault flag output for channel B. Pulled LOW during over-current, thermal shutdown, or UVLO on channel B. Requires external pull-up (typ 10 kΩ). Absolute max VFLG = 7 V, IFLG = 50 mA. |
| 4 | CTLB | input | Enable / control input for channel B high-side switch. Active-LOW on the AIC1519N-0 variant. Logic thresholds: VIL ≤ 0.8 V, VIH ≥ 2.4 V; input current ~0.01 µA; absolute max -0.3 V to +7 V. |
| 5 | OUTB | power_out | Switched high-side power output for channel B (drain of internal PMOS). Delivers VIN through 110 mΩ (typ) RDS(ON); rated 1.4 A continuous, 1.75 A typical current-limit threshold. Requires a 33 µF (or larger) local bulk capacitor per USB spec. |
| 6 | GND | power_in | Device ground reference for all logic and power circuits. |
| 7 | IN | power_in | Common supply input for both channel switches and internal control circuitry. Operating range 3.1 V to 6.0 V (typ 5 V USB); UVLO threshold ~2.85 V rising / 2.65 V falling. Absolute max 7.0 V. Bypass with 0.1 µF close to the pin. |
| 8 | OUTA | power_out | Switched high-side power output for channel A (drain of internal PMOS). 110 mΩ (typ) RDS(ON), 1.4 A continuous, 1.75 A typical current-limit. Requires a 33 µF (or larger) local bulk capacitor per USB spec. |
