Automotive Qualified AUIRS2117S and
AUIRS2118S Deliver Reliable Compact
Solution
The AUIRS2117S and AUIRS2118S 600V ICs were
designed for automotive gate driver applications
including direct injection and brushless DC motor
drivers. These high side drivers feature very short
turn-on and turn-off propagation time to drive the
MOSFET or IGBT at a much higher frequency to
shrink system size by enabling the use of smaller
filtering components.

Features
Advantages
• Floating channel designed for bootstrap operation
• Fully operational to +600V
• Output current capability of 290mA/600mA
• The AUIRS2117S features output signals in phase with the input
signal and CMOS Schmitt-triggered inputs with pull-down.
• The AUIRS2118S features output signals out of phase with the
input signal and CMOS Schmitt-triggered inputs with pull-up.
• The new ICs feature proprietary high-voltage integrated circuit
(HVIC) and latch immune CMOS technologies to offer ruggedized
monolithic construction and benchmark negative voltage spike
immunity for reliable operation even under extreme switching
conditions and short circuit events.
• The floating channel can be used to drive an N-channel power
MOSFET or IGBT in the high-side configuration, operating up to
600V.
• Tolerant to negative transient voltage – dV/dt
immune
• Gate drive supply range from 10V to 20V
• Unvervoltage lockout
• CMOS Schmitt-triggered input with pull-down
(AUIRS2117S) or pull-up (AUIRS2118S)
• Output in phase with inputs (AUIRS2117S)
• Output out of phase with inputs (AUIRS2118S)
• Lead free, RoHS compliant
• Automotive Qualified per AEC-Q100
