ADuM4136

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

Manufactured by:

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.

Applications

  • MOSFET/IGBT gate drivers
  • Photovoltaic (PV) inverters

Product Details

The EVAL-ADuM4136EBZ evaluation board supports the ADuM4136 single-channel gate driver, which is specifically optimized for driving insulated gate bipolar transistors (IGBTs). Analog Devices, Inc., iCoupler® technology provides isolation between the input signal and the output gate driver.


The ADuM4136 provides operation with voltages of up to 35 V. With a dual-rail supply, the negative rail can go as low as −15 V, providing robust turn off of the IGBT.


The EVAL-ADuM4136EBZ evaluation board facilitates testing of the desaturation circuitry with pads available for standard desaturation detection. The evaluation board has layout locations for three different types of discrete switches, allowing for a wide range of device testing. Screw terminals provide easy access to supplying the secondary side with either a single or dual supply. 


For complete information about the ADuM4136, refer to the product data sheet that should be consulted in conjunction with user guide UG-1019 when using the evaluation board.
