TA8050P

TA8050P TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8050P 1.5A MOTOR DRIVER WITH BRAKE FUNCTION The TA8050P is a 1.5A motor driver which directly drives 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 functions. FEATURES l Bidirectional DC motor driver l Current capacity : 1.5A l Four modes : Forward, Reverse, Stop, and Brake Weight: 1.9 g (typ.) l Recommended operating supply voltage range: VCC = 6V to 16V l Protective functions : Thermal Shutdown, Short Circuit Protection, and Overvoltage Shutdown l Built-in diode for counteracting counter electromotive force l Plastic HSIP-7 pin BLOCK DIAGRAM AND PIN LAYOUT 1 2002-03-12 PIN DESCRIPTION TA8050P PIN No. 1 2 3 4 5 6 7 SYMBOL DI1 DI2 M (+) GND M (−) NC VCC DESCRIPTION Output status control pin. Connects to a PNP-type voltage comparator. Connects to the DC motor. Both the sink and the source have a current capacity of 1.5A. Diodes for absorbing counter electromotive force are contained on the VCC and GND sides. Grounded Connects to the DC motor together with pin 3 and has the same function as pin 3. This pin is controlled by the inputs from pins 1 and 2. Not connected. (Electrically, this pin is completely open.) Power supply pin. This pin has a function to turn off the output when t...
