Подробнее о продукте

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 VOA and VOB 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, VOA and VOB, 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.
