Freescale Semiconductor Technical Data 1.0 A 6.8 V H-Bridge Motor Driver IC The 17511 is a monolithic H-Bridge designed to be used in portable electronic applications to control small DC motors or bipolar step motors. End applications include head positioners (CDROM or disk drive), camera focus motors, and camera shutter solenoids. The 17511 can operate efficiently with supply voltages as low as 2.0 V to as high as 6.8 V. Its low RDS(ON) H-Bridge output MOSFETs (0.46 Ω typical) can provide conti.
