AP74700QW6-7

Diodes Incorporated · Isolators - Gate Drivers · SOT-26

AP74700QW6-7 from Diodes Incorporated, in a SOT-26. 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 VCP power_out Charge pump voltage output pin. Connect an external capacitor (min 0.1 µF) from VCP to ANODE. Charge pump generates ~V_ANODE + 7 V typical to drive the external N-MOSFET gate (V_VCP-V_ANODE min 8 V at I_VCP ≤ 30 µA).
2 GND power_in Ground pin. Device reference.
3 EN input Enable pin, active high. V_IH ≥ 1.3 V (typ 2.3 V) enables the controller, V_IL ≤ 1.45 V (typ 1.05 V) disables. Hysteresis 0.52 V typ. Enable sink current ~3 µA typ at V_EN = 12 V. Absolute max -0.3 V to +65 V (with ANODE > 0 V).
4 CATHODE input CATHODE sense pin. Connect to the drain of the external N-channel MOSFET (output/load side). Used by the internal comparators/Gm amplifier to sense the MOSFET V_DS for forward regulation (~20 mV), full conduction (50 mV) and reverse-current blocking (-10 mV) thresholds. Operating range -60 V to +60 V vs GND.
5 GATE output Gate driver output. Connects to the gate of the external N-channel MOSFET. Peak source current ~11 mA, peak sink current ~1.85 A for fast reverse-current turn-off (<0.75 µs). Discharge switch R_DIS ≤ 2 Ω. GATE-to-ANODE clamped ≤ 15 V.
6 ANODE power_in Input supply and ANODE sense pin. Connects to the source of the external N-channel MOSFET (input/battery side). Operating input voltage 4 V to 60 V (start-up 3.9 V), absolute max -65 V to +65 V. Requires input capacitor ≥ 22 nF. Quiescent current ~80 µA typ, shutdown ~0.7 µA typ.
