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
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
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.
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).
