G2005 Global Mixed-mode Technology Inc. 5+1CH serial input motor driver IC for DSC Features General Description Built-in 4 full-swing/constant voltage drivers G2005 is a 5+1-channel H-Bridge motor drivers IC for the digital camera and so on. It has four full-swing/constant voltage drivers and two full-swing/constant current drivers. G2005 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 2 constant current drivers for shutter or IRIS Low on-resistance (1.2Ω, sum of on-resistance of up side and bottom side) Output current：IOUT<=0.8A(max.) for each channel Built-in thermal shutdown (TSD, 150°C) Built-in CC mode weak excitation 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 All power supply systems (VCC, VM12, VM3, VM45) can be set up with an independent power supply Power save mode corresponds by serial control setup PI (photo interrupter drive) 3 channel built-in. Small 32TQFN (4×4mm) is adopted Ordering Information ORDER NUMBER MARKING G2005K11U 2005 Note: K1: TQFN4X4-32 1: Bonding Code U: Tape & Reel TEMP.
