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.

Parameter Temperature Trends
Figures illustrated in this chapter provide information on the experimental performance of the IC. The line plotted in
each figure is generated from actual lab data. A large number of individual samples were tested at three
temperatures (-40 ºC, 25 ºC, and 125 ºC) in order to generate the experimental curve. The line consists of three
data points (one data point at each of the tested temperatures) that have been connected together to illustrate the
understood trend. The individual data points on the curve were determined by calculating the averaged
experimental value of the parameter (for a given temperature).
