1.5A Dual High Speed
MOSFET Drivers
LLC
AS4426 / AS4427 / AS4428
FEATURES
DESCRIPTION
The
AS4426
series are dual CMOS drivers are designed to
drive capacitive, resistive and inductive loads switching
1000pF gate capacitances in under 30ns while providing low
impedances in both the ON and OFF states to insure the
MOSFET’s intended state will not be affected. All terminals
are fully protected up to 4kV of ESD.
