1A Motor Drive IC for Motor Applications
MB3853
s 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.
s FEATURES
