G2012 Global Mixed-mode Technology Inc. 4+2CH serial input motor driver IC for DSC Features General Description Built in 4+1 full-swing/constant voltage drivers G2012 is a 4+2-channel H-Bridge motor drivers IC for the digital camera and so on. It has four full-swing/constant voltage drivers and one full-swing/constant current drivers. G2012 can be operated in serial control mode or partial exterior control mode. When operating in partial 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. switched by serial control with brake function Built in 1 constant current drivers for shutter or IRIS Low on-resistance (1.2Ω, sum of on-resistance of upside and bottom side) Output current：IOUT<=0.8A(max.) for each channel Build-in thermal shutdown (TSD, 150°C) CH1/2 corresponds to STM control of 2-2 phase or 1-2 phase Built in exclusive control mode: CH13/23 Æ the combination control mode of 6CH is set Power save mode corresponds by serial control setup PI (photo interrupter drive) 1 channel built-in. Small 20TQFN (3×3mm) is adopted Ordering Information ORDER NUMBER Applications MARKING G2012RZ1U 2012 Note: RZ: TQFN3X3-20 1: Bonding Code U: Tape & Reel Stepping motor driver/ DC motor driver motor driver for DSC TEMP.
