EVAL-ADuM4221-1EBZ User Guide UG-1857 One Technology Way P.O. Box 9106 Norwood, MA 02062-9106, U.S.A. Tel: 781.329.4700 Fax: 781.461.3113 www.analog.com Evaluating the ADuM4221-1 Isolated, Half Bridge Gate Driver with Adjustable Dead Time, 4 A Output EVAL-ADuM4221-1EBZ operates with square waves and dc FEATURES values on the PWM and DISABLE pins. Adjustable dead time The ADuM4221-1 operates with an input supply ranging from Output voltage range to 35 V Screw terminals for easy connectivity 2.5 V to 6.5 V, providing compatibility with lower voltage systems. Pad placement for external series gate resistors The logic level voltage at the input PWM pin controls the VOA Pad placement for capacitive load testing and VOB outputs. The driver has a DISABLE input pin that, if held Supports TO-220 or TO-252 IGBTs or MOSFETs high, shuts the device off regardless of the input on the channels. Bootstrap option The input on the PWM pin generates the complementary Jumper placement for easy half bridge setup outputs, V and V , with basic overlap protection, and the OA OB dead time (DT) pin on the primary side allows an adjustable EVALUATION KIT CONTENTS dead time between these output transitions. EVAL-ADuM4221-1EBZ evaluation board The ADuM4221-1 provides operation with voltages of up to EQUIPMENT NEEDED 35 V on the secondary side. The EVAL-ADuM4221-1EBZ has a provision for the high-side supply to be bootstrapped to the low- Suggested test equipment side supply. The EVAL-ADuM4221-1EBZ facilitates testing of Primary side power supply: 0 V to 6.5 V at 100 mA the propagation delay, drive strength, dead time operation, and 2 secondary side supplies: 0 V to 35 V at 250 mA input logic of the device. Because the EVAL-ADuM4221-1EBZ Square wave generator: 0 V to 5 V has footprints for insulated gate bipolar transistors (IGBTs) and GENERAL DESCRIPTION metal-oxide semiconductor field effect transistors (MOSFETs) The EVAL-ADuM4221-1EBZ supports the ADuM4221-1 half in TO-220 and TO-252 packages, the ADuM4221-1 can be bridge gate driver that employs Analog Devices, Inc., iCoupler evaluated with many different power devices. technology to provide independent and isolated high-side and For complete information about the ADuM4221-1, refer to the low-side output. The EVAL-ADuM4221-1EBZ is populated with ADuM4221-1 data sheet in conjunction with this user guide the ADuM4221-1, which has a single PWM input and dead time when using the EVAL-ADuM4221-1EBZ. control. The EVAL-ADuM4221-1EBZ supplies jumpers and screw terminals to configure different drive conditions. The EVAL-ADUM4221-1EBZ PHOTOGRAPH Figure 1.
