Overview

The LB1934T is a low-voltage, low-saturation forward/
reverse dri v er IC with b uilt-in 1.5-channel bridg e. Its com­pact, low-profile package makes it ideal for use in compact
cameras powered by 3V lithium batteries.
Using direct microcontroller drive, it is possible to control
standby, forward rotation, reverse rotation, and braking of
two motors for film rewind and lens dri ve b y means of only
three control signals. The 0.5-channel section of the 1.5­channel bridge can be divided into sink/source output, al­lowing configurations such as 1-channel bridge + sink out-

put + source output.

Features

• Low voltage drive possible.
When using same power supply for VCC and VS :
VCC=VS=1.4V min.
When using separate power supply for VCC and VS :
VS=1.0V min., VCC=1.4V min.

• Low saturation v oltage : residual v oltage (upper side tran­sistor + lower side transistor) =0.5V typ. at Io=1A.

• Zero power dissipation in standby mode.

• Direct microcontroller drive possible (any strength rela­tionships of voltage supported between microcontroller
control signal and VCC or VS).

• Logic power supply and motor power supply can be sup­plied at separate pins.

• Built-in thermal protection circuit.

• Number of control signals can be optimized for the set.
“2-motor control” or “1-motor + 2-load control” can be
implemented by 3 control signals.
In addition to the above, 4 control signals allow
implemention of a “input ignore mode” where two con­trol signals are used in conjunction with other IC input
signals.

• Built-in spark killer diode.

• Compact, low-prof ile package (TSSOP-20 ; thickness=1.1
mm typ.)
