5+1CH serial input motor driver IC for DSC

Features

General Description

Built-in 4 full-swing/constant voltage drivers

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)

G2028 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.

G2028 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.

Output current：I_OUT<=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.
