ADuM3220/ADuM3221 是基于ADI公司
iCoupler® 技术的4 A隔离式双通道门极
drive。这些隔离器件结合了高速CMOS工艺和单片变压器技术，能够提供比脉冲变压器和门极驱动器组合等其它解决方案更优异的性能特性。
The ADuM3220/ADuM3221 isolators provide two independent isolation channels. The maximum propagation delay is 60 ns, and the channel-to-channel matching is 5 ns. Compared to gate drivers with a high-voltage level-shifting approach, the ADuM3220/ADuM3221 have the advantage of true current isolation between the inputs and outputs, enabling voltage conversion across the isolation gate. The ADuM3220 has pass-through protection logic, while the ADuM3221 does not. Both devices provide the default low-level output characteristics required for gate drive applications. The ADuM3220/ADuM3221 has an input supply voltage range of 3.0 V to 5.5 V and is compatible with low-voltage systems. The ADuM3220A/ADuM3221A have an output supply voltage range of 5 V to 18 V. The DuM3220B/ADuM3221B have an output supply voltage range of 8 V to 18 V.
The ADuM3220/ADuM3221 is rated for a junction temperature range of −40°C to +125°C.
