GENERAL DESCRIPTION

The ADuM4146 is a single-channel gate driver specifically optimized

for driving silicon carbide (SiC), metal-oxide semiconductor

field effect transistors (MOSFETs). Analog Devices, Inc., iCoupler?

technology provides isolation between the input signal and the

output gate drive.

The ADuM4146 includes a Miller clamp to provide robust SiC turn

off with a single-rail supply when the gate voltage drops to less

than 2 V. Operation with unipolar or bipolar secondary supplies is

possible with or without the Miller clamp operation.

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 ADuM4146 is a desaturation detection circuit

that provides protection against high voltage short-circuit SiC operation.

The desaturation protection contains noise reducing features,

such as a 300 ns masking time after a switching event to mask

voltage spikes due to initial turn on (see Figure 17). An optional

internal 500 μA 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 undervoltage lockout (UVLO) is set to 14.5 V (typical)

for Grade A and is set to 11.5 V (typical) for Grade B and

Grade C with common SiC and insulated gate bipolar transistor

(IGBT) levels taken into consideration.
