High Speed Coil Drivers
The EL7240/EL7241 high speed coil
drivers accept logic inputs which
independently control a pair of 3
PMOS FET's. The output transistors share a common
source, making these devices well suited for “current
steering” and analog switching applications. The typical
clamping diodes to ground are removed, thus allowing pins
(6) and (7) to swing negative. This feature is desirable when
driving “center-tapped” coils referenced to ground. The logic
“NAND” input configuration can be used to “enable” the
outputs. The EL7240 and EL7241 differ only by their logic
polarity.
