• Available in 3-mm x 3-mm package
• Interlock or cross-conduction protection
• Enable/disable functionality
• Absolute maximum negative voltage handling on HS (-7 V)
• 5-V typical under voltage lockout
• 20-ns typical propagation delay
• 11-ns rise, 8-ns typical fall time with 1000-pF load
• 1-ns typical delay matching
• 2.6-A sink, 1.6-A source output currents
• Absolute maximum boot voltage 110 V
• Low current (7-µA) consumption when disabled
• Integrated bootstrap diode

• Motor drives and power tools
• Switch-mode power supplies
• Auxiliary inverters
