EVAL-ADuM4221-2EBZ User Guide UG-1858 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 ADuM4221-2 Isolated, Half Bridge Gate Driver, 4 A Output to configure different drive conditions. The EVAL-ADuM4221- FEATURES 2EBZ operates with square waves and dc values on the V , V , IA IB Output voltage range to 35 V and DISABLE pins. Screw terminals for easy connectivity Pad placement for external series gate resistors The ADuM4221-2 operates with an input supply ranging from Pad placement for capacitive load testing 2.5 V to 6.5 V, providing compatibility with lower voltage Supports TO-220 or TO-252 IGBTs or MOSFETs systems. Logic level voltages at the input pins control the VOA Bootstrap option and VOB outputs. The driver has a DISABLE input pin that, if Jumper placement for easy half bridge setup held high, shuts the device off regardless of the input on the channels. EVALUATION KIT CONTENTS The ADuM4221-2 provides operation with voltages of up to EVAL-ADuM4221-2EBZ evaluation board 35 V on the secondary side. The EVAL-ADuM4221-2EBZ has a EQUIPMENT NEEDED provision for the high-side supply to be bootstrapped to the low- side supply. The EVAL-ADuM4221-2EBZ facilitates testing of Suggested test equipment the propagation delay, drive strength, and input logic of the Primary side power supply: 0 V to 6.5 V at 100 mA device. Because the EVAL-ADuM4221-2EBZ has footprints for 2 secondary side supplies: 0 V to 35 V at 250 mA insulated gate bipolar transistors (IGBTs) and metal-oxide Square wave generator: 0 V to 5 V semiconductor field effect transistors (MOSFETs) in TO-220 GENERAL DESCRIPTION and TO-252 packages, the ADuM4221-2 can be evaluated with The EVAL-ADuM4221-2EBZ supports the ADuM4221-2 half many different power devices. bridge gate driver that employs Analog Devices, Inc., iCoupler For complete information about the ADuM4221-2, refer to the technology to provide independent and isolated high-side and ADuM4221-2 data sheet in conjunction with this user guide low-side outputs. The EVAL-ADuM4221-2EBZ is populated when using the EVAL-ADuM4221-2EBZ. with the ADuM4221-2, which has the V and V inputs.
