ADP3654 is a high current, dual channel, 4A MOSFET driver. It has standard pinout, high current drive capability, accurate UVLO comparator, 3.3V compatible input, 10ns typical rise and fall time, matched channel delay, fast propagation delay, 4.5V to 18V supply voltage, parallelable dual outputs, -40°C to +125°C junction temperature and enhanced package, suitable for AC-to-DC switch mode power supplies, DC-to-DC power supplies, synchronous rectification and motor drives.
The ADP3654 high‑current, dual MOSFET driver from Analog Devices provides fast switching for two independent N‑channel power MOSFETs. It features a standard 8‑lead SOIC or MINI‑SOIC package, a wide 4.5 V‑18 V supply range, 3.3 V‑compatible inputs, and built‑in UVLO with hysteresis for safe start‑up and shut‑down.
The datasheet includes detailed specifications, pin descriptions, timing diagrams, absolute maximum ratings, and layout recommendations. It also provides an ordering guide for the SOIC_N_EP and MINI_SO_EP package options.
