High Speed Coil Drivers

The EL7240/EL7241 high speed coil

drivers accept logic inputs which

independently control a pair of 3

Ω

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.
