Features
„ Built in 4 full-swing/constant voltage drivers for
simulation micro steeping motor. (STM OIS)
„ Built in 1 full-swing/constant current drivers for
shutter or IRIS
„ Built in 3+1 full-swing/constant voltage drivers
switched by serial control with brake function.
„ Low on-resistance (1.2Ω, sum of on-resistance
of upside and bottom side)
„ Output current ： IB_OUTB<=0.8A(max.) for each
channel
„ Build-in thermal shutdown (TSD, 150°C)

„ All power supply systems (VCC, VM12,
VM345,VM6789) can be set up with an
independent power supply
„ Power save mode corresponds by serial
control setup
„ Built in POR (power on reset) function.
„ I2C interface
„ PI (photo interrupter driver) 2 channel built-in
„ TQFN(5*5mm)-40 package is adopted
General Description
G2022 is a 8i+1-channel H-Bridge motor drivers IC
for the digital camera and so on. It has eight
full-swing/constant voltage drivers and one full-
swing/constant current/constant voltage drivers.
G2022 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.
The serial interface (I2C) that operates at clock
rates up to 400 KHz.
