Elantec EL7202C High speed, dual channel power mosfet driver Datasheet

High Speed, Dual Channel Power MOSFET Drivers
Features
General Description
# Industry standard driver
replacement
# Improved response times
# Matched rise and fall times
# Reduced clock skew
# Low output impedance
# Low input capacitance
# High noise immunity
# Improved clocking rate
# Low supply current
# Wide operating voltage range
The EL7202C/EL7212C/EL7222C ICs are matched dual-drivers ICs 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.

Important Note:
All parameters having Min/Max specifications are guaranteed. The Test Level column indicates the specific device testing actually
performed during production and Quality inspection. Elantec performs most electrical tests using modern high-speed automatic test
equipment, specifically the LTX77 Series system. Unless otherwise noted, all tests are pulsed tests, therefore TJ e TC e TA.
