AUIR0815S Datasheet, PDF (1/19 Pages) International Rectifier – BUFFER GATE DRIVER IC

Automotive Grade
AUIR0815S
BUFFER GATE DRIVER IC
Features
• High peak output current > 10A
• Low propagation delay time
• Negative turn off bias can be applied to VEE using an external supply
• Two output pins permit to choose different Ron and Roff resistors.
• Low supply current
• Undervoltage lockout
• Continuous ‘on’ capability
• Suitable for high power inverter applications in conjunction with an
external pre-driver
• Lead-Free, RoHS Compliant
• Automotive qualified
Description
The AUIR0815 buffer gate driver family, in conjunction with a pre-driver
stage, is suited to drive a single half bridge in power switching
applications. These buffer gate drivers incorporate the ability to enter into
a low quiescent current mode.
