The ADP3629/ADP3630/ADP3631 are dual, high current, high speed drivers, capable of driving two independent N-channel power MOSFETs. The devices feature industry-standard-compatible pinouts, high current drive capability, precise threshold shutdown comparator, UVLO with hysteresis, overtemperature warning signal, overtemperature shutdown, 3.3 V-compatible inputs, rise time and fall time of 10 ns typical at 2.2 nF load, fast propagation delay, matched propagation delays between channels, supply voltage of 9.5 V to 18 V, dual outputs that can be operated in parallel (ADP3629/ADP3630), and an operating temperature range of -40°C to +85°C. The devices are suitable for use in AC-to-DC switch mode power supplies, DC-to-DC power supplies, synchronous rectification, and motor drive applications.
The ADP3629, ADP3630 and ADP3631 are dual, high‑current, high‑speed MOSFET drivers that can drive two independent N‑channel power MOSFETs. They feature industry‑standard pinout, precise UVLO with hysteresis, over‑temperature warning and shutdown, and fast propagation delays.
The devices operate from a 9.5 V to 18 V supply, provide up to 2 A peak source/sink current, and include detailed thermal and layout guidance for reliable operation in AC‑DC and DC‑DC power supplies, motor drives, and synchronous rectifiers.
