The design is optimal for stepper-motor applications, such as cameras, printers, FDDs, or other portable devices. Features and Benefits z Low voltage operation ( VDD min = VS1 min = VS2 min = 1.5V ) z Low saturation voltage ( Upper transistor + low transistor residual voltage; 0.5V typ. at 400mA) z Parallel connection ( two-channel driver: Upper transistor + low transistor residual; 0.6V typ. a...
