UNISONIC TECHNOLOGIES CO., LTD UA9287 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.
