ANALOG DEVICES EVAL-ADUM4122EBZ Evaluation Board, ADuM4122ARIZ, Isolated Gate Driver, Power Management

EVAL-ADUM4122EBZ evaluation board supports the ADuM4122 isolated gate driver with slew rate control. iCoupler® technology provides isolation between the ADuM4122 input signal and the output gate driver. The evaluation board supplies jumpers and screw terminals to configure different drive conditions. The EVAL-ADuM4122EBZ board operates with square waves and dc values on the VIN+ and active-low SRC pins. The ADuM4122 is operational with voltages of up to 35 V. Logic level voltages at the VIN+ pin control the VOUT output. The active-low SRC pin controls whether the VOUT_SRC pin is either set to high-Z or follows the logic of the user supplied pulse-width modulation (PWM) input at VIN+. When the external series gate resistors combine the outputs from the VOUT and VOUT_SRC pins, one isolated gate driver is then able to have two easily selectable slew rates. The EVAL-ADuM4122EBZ board tests the propagation delay, drive strength, slew rate selection, and input logic of the device.
