1A Motor Drive IC for Motor Applications
MB3853
■ DESCRIPTION
The FUJITSU MB3853 is a motor drive IC with two power driver channels capable of sink/source operation, for
use in two-channel independent operation or H-type drive operation.
The control system and output system have independent power supplies, allowing the control system to be set
to low-voltage operation to conserve power.
Protective circuits are provided for temperature, overvoltage, and overload current, with an open collector type
monitoring terminal.
The MB3853 is designed for use with motors in AV products, office automation products, or cameras, and is also
an ideal IC for use in automated vending equipment and other unmanned operating devices.
■ FEATURES
• Circuit configuration
Two sets of built-in control circuits and power circuits
Built-in fly-back diode
• Functions
Can drive two motors independently or in H-type drive configurations
Built-in inhibitor function

■ FUNCTIONAL DESCRIPTION
The MB3853 provides two methods for controlling motors. The IC can be connected to two motors and drive
each motor independently, or connected to one motor in an H-type connection and drive the motor in forward
and reverse directions.
1. Sample connection to 2 motors for run-stop control.

WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
