TA8081P

TA8081P TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TA8081P 0.7A MOTOR DRIVER WITH DIAGNOSIS The TA8081P is a 0.7A motor driver which directly drivers a bidirectional DC motor. Inputs DI1 and DI2 are combined to select one of forward, reverse, stop, and brake modes. Since the inputs are TTL−compatible, this IC can be controlled directly from a CPU or other control system. The IC also has various protective, self−diagnostic, and standby functions. FEATURES l Bidirectional DC motor driver. l Current capacity: 0.7A (max) l Low standby current: 100µA (max) Weight: 1.0 g (typ.) l Four operation modes: Forward, reverse, stop, and brake. l Recommended operating supply voltage range: VCC = 6 V to 16 V l Protective functions: Thermal shutdown, short-circuit protection, and over-voltage shutdown. l Built−in counter electromotive force absorption diodes. l Self−diagnostic output: On short-circuit detection. l Plastic DIP-16pin.

This pin is completely isolated from VCC. When this pin is opened or grounded, the output turns off, thus reducing the current consumption to 100µA or less. If standby mode is not needed, the pin is connected to VCC. Self-diagnostic output pin. When the output current becomes 1.5A or more, this pin outputs a protection switchi...
