High Speed, Dual Channel Power MOSFET
Drivers
The EL7202/EL7212/EL7222 ICs are matched dual-drivers
that improve the operation of the industry standard DS0026
clock drivers. The Elantec versions are very high speed
drivers capable of delivering peak currents of 2.0 amps into
highly capacitive loads. 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. These
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.
