TA8080K

TA8080K TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8080K 1.0A MOTOR DRIVER WITH BRAKE FUNCTION The TA8080K is a 1.0A 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 1.0A current capacity. l Four operation modes brake. : Forward, reverse, stop, and Weight: 2.2 g (typ.) l Recommended operating supply voltage range: VCC = 6V to 16V l Protective functions : Thermal-shutdown, short-circuit protection, and over-voltage shutdown. l Built-in counter electromotive force absorption diodes. l Plastic package HSIP-7pin. BLOCK DIAGRAM AND PIN LAYOUT 1 2002-02-27 PIN DESCRIPTION TA8080K 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 1.0A. 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 t...
