Supplies both switch channels; operating range 2.7 V to 5.5 V (abs max 6.5 V). Bypass with 0.1 µF and bulk 10 µF near pin. |+| 3 | EN1 | input | Switch 1 enable input. Active high on AP2172 (this variant). VIL ≤ 0.8 V, VIH ≥ 2 V. Input leakage ≤ 1 µA. |+| 4 | EN2 | input | Switch 2 enable input. Active high on AP2172 (this variant). VIL ≤ 0.8 V, VIH ≥ 2 V. Input leakage ≤ 1 µA. |+| 5 | FLG2 | output | Switch 2 over-current and over-temperature fault report. Open-drain output, active low when triggered. Requires external pull-up (typ. 10 kΩ). 7 ms typical blanking time. IFLG = 10 mA max, RFLG ≈ 30 Ω typ. |+| 6 | OUT2 | power_out | Switch 2 voltage output. Delivers up to 1.0 A continuous (1.5 A typ current limit). Bypass with 0.1 µF plus bulk 68 µF at load per USB requirements. |+| 7 | OUT1 | power_out | Switch 1 voltage output. Delivers up to 1.0 A continuous (1.5 A typ current limit). Bypass with 0.1 µF plus bulk 68 µF at load per USB requirements. |+| 8 | FLG1 | output | Switch 1 over-current and over-temperature fault report. Open-drain output, active low when triggered. Requires external pull-up (typ. 10 kΩ). 7 ms typical blanking time.
