ADUM4136BRWZ-RL

门驱动器 Isolated Half-bridge Gate Driver

Product Details

The ADuM4136 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.

Operation with unipolar or bipolar secondary supplies is possible, allowing negative gate drive if needed.

The Analog Devices chip scale transformers also provide isolated communication of control information between the high voltage and low voltage domains of the chip. Information on the status of the chip can be read back from dedicated outputs. Control of resetting the device after a fault on the secondary side is performed on the primary side of the device.

Integrated onto the ADuM4136 is a desaturation detection circuit that provides protection against high voltage short-circuit IGBT operation. The desaturation protection contains noise reducing features such as a 312 ns typical masking time after a switching event to mask voltage spikes due to initial turn-on. An internal 537 μA typical current source allows low device count, and the internal blanking switch allows the addition of an external current source if more noise immunity is needed.

The secondary UVLO is set to 12 V with common IGBT threshold levels taken into consideration.
