LINEAR INTEGRATED CIRCUIT
REVERSIBLE MOTOR DRIVER
DESCRIPTION
The UTC UA9287 is designed for driving reversible-motor with a
maximum output current of 1A. There are four output modes decided
by two logic inputs: forward, reverse, stop (idling), and brake. When
the motor is in stop mode, the current consumption can be
suppressed.
SOP-8
FEATURES
* With the VREF Pin, Output Voltage can be Set Arbitrarily.
* The Current Dissipation can be Suppresses with Power Saving
Circuit Built-In when in Stop Mode.
* Thermal Shutdown Circuit Built-In.
* Interfaces with TTL Devices.
