EL7412
High Speed, Four Channel Power
MOSFET Drivers
The EL7412 contains (4) high performance matched drivers.
These very high speed drivers are capable of delivering
peak currents of 2.0 amps into highly capacitive loads and
are ideally suited for "Full bridge' and ultrasound
applications. The high speed performance is achieved by
means of a proprietary "Turbo-Driver' circuit that speeds up
input stages by tapping the wider voltage swing at the
output. Improved speed and drive capability are enhanced
by matched rise and fall delay times. The matched delays
maintain the integrity of input-to-output pulse-widths to
reduce timing errors and clock skew problems. This
improved performance is accompanied by a 10 fold
reduction in supply currents over bipolar drivers, yet without
the delay time problems commonly associated with CMOS
devices. Dynamic switching losses are minimized with non-
overlapped drive techniques.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J-Std-020C.
