G2002/G2002B Global Mixed-mode Technology 5+1CH serial input motor driver IC for DSC Features General Description Build-in one micro-steps drive mode is possible G2002/G2002B is a 5+1-channel H-Bridge motor drivers IC for the digital camera and so on. It has one micro-stepping driver, two full-swing/constant voltage drivers and one full-swing/constant current drivers. G2002 /G2002B 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. from 2-2 phase stepper drive to maximum 256 resolution micro-steps. Built in 2 full-swing/constant voltage drivers 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) 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 28TQFN (4×4mm) is adopted Build-in POR (power on reset).
