Preliminary Product Information Serial Input 6CH Motor Driver for DSC Features
* * * * * * * * * * * * Built in 5 full-swing/constant voltage drivers switched by serial control, three of those drivers being with brake function. Built in 1 constant current driver for shutter. Low on-resistance(1.2 , sum of on-resistance of upside and bottom side) Build-in thermal shutdown (TSD, 15 ) CH1~CH4 corresponds to control of 2-2 phase or 1-2 phase. All power supply systems(VCC, VM 4) can be set up with an independent power supply. Power save mode corresponds by serial control setup and exterior pin control. All initial serial control setting is set to "0", so IC can work if power save pin pulls high. The reference voltage, Vref, to be divided for exterior VC setup. VC can be setup in DAC from built-in voltage 1V. PI (photo interrapter drive) 2CH built-in. ON resistance change is possible. Small 40QFN (6 6mm) is adopted.
General Description
AT5557 is a 6-channel H-Bridge motor drivers IC for the digital camera and so on. It has five full-swing/constant voltage drivers and one constant current driver. AT5557 can be operated in serial control mode or full exterior control mode. When operating in full exterior control mode, the mode of each CH is fixed by initial serial control setting. When operating in serial control mode, the mode of each driver can be setting by serial control.
Applications
* Stepping motor driver/ DC motor driver motor driver for DSC
