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

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：I_OUT<=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).
