AP2172SG-13

Diodes Incorporated · AC-DC Controllers and Regulators · SOIC-8

AP2172SG-13 from Diodes Incorporated, in a SOIC-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 GND power_in Device ground reference.
2 IN power_in Voltage input pin. 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. IFLG = 10 mA max, RFLG ≈ 30 Ω typ.
