G2018 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 G2018 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. G2018 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 1024 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 Built in CH3 DCM FLL function 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 32TQFN (4×4mm) is adopted Build-in POR (power on reset). Ordering Information ORDER NUMBER MARKING G2018K11U 2018 Note: K1: TQFN4X4-32 1: Bonding Code U: Tape & Reel TEMP.
