ADUM4135BRWZ

门驱动器 Isolated Half-bridge Gate Driver

Single-/Dual-Supply, High Voltage Isolated  IGBT Gate Driver with Miller Clamp

GENERAL DESCRIPTION ADUM4135BRWZ

The ADuM4135 is a single-channel gate driver specifically

optimized for driving insulated gate bipolar transistors (IGBTs).

Analog Devices, Inc., iCoupler® technology provides isolation

between the input signal and the output gate drive.

The ADuM4135 includes a Miller clamp to provide robust

IGBT turn-off with a single-rail supply when the gate voltage

drops below 2 V. Operation with unipolar or bipolar secondary

supplies is possible, with or without the Miller clamp operation.
