Product Details

The EVAL-ADuM4221-1EBZ supports the ADuM4221-1 half bridge gate driver that employs Analog Devices, Inc., iCoupler^® technology to provide independent and isolated high-side and low-side output. The EVAL-ADuM4221-1EBZ is populated with the ADuM4221-1, which has a single PWM input and dead time control. The EVAL-ADuM4221-1EBZ supplies jumpers and screw terminals to configure different drive conditions. The EVAL-ADuM4221-1EBZ operates with square waves and dc values on the PWM and DISABLE pins.

The ADuM4221-1 operates with an input supply ranging from 2.5 V to 6.5 V, providing compatibility with lower voltage systems. The logic level voltage at the input PWM pin controls the V_OA and V_OB outputs. The driver has a DISABLE input pin that, if held high, shuts the device off regardless of the input on the channels. The input on the PWM pin generates the complementary outputs, V_OA and V_OB, with basic overlap protection, and the dead time (DT) pin on the primary side allows an adjustable dead time between these output transitions.

The ADuM4221-1 provides operation with voltages of up to 35 V on the secondary side. The EVAL-ADuM4221-1EBZ has a provision for the high-side supply to be bootstrapped to the low-side supply. The EVAL-ADuM4221-1EBZ facilitates testing of the propagation delay, drive strength, dead time operation, and input logic of the device. Because the EVAL-ADuM4221-1EBZ has footprints for insulated gate bipolar transistors (IGBTs) and metal-oxide semiconductor field effect transistors (MOSFETs) in TO-220 and TO-252 packages, the ADuM4221-1 can be evaluated with many different power devices.

For complete information about the ADuM4221-1, refer to the ADuM4221-1 data sheet in conjunction with the user guide when using the EVAL-ADuM4221-1EBZ.
