TA8050F

TA8050F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8050F 1.5 A DC Motor Driver with Brake Function The TA8050F is a 1.5 A 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 · · · · · · · Bidirectional DC motor driver Current capacity Four modes : 1.5 A : Forward, Reverse, Stop, and Brake Weight: 0.79 g (typ.) Recommended operating supply voltage range : VCC = 6~16 V Protective functions : Thermal Shutdown, Short Circuit Protection, and Overvoltage Shutdown Built-in diode for counteracting counter electromotive force HSOP-20 Pin power flat package Block Diagram and Pin Layout M (-) 20 19 18 17 16 GND FIN M (+) 15 14 13 12 11 Thermalshutdown and over-voltage protection Short protection Control logic 1 VCC 2 3 VCC 4 5 FIN GND 6 7 8 9 10 DI1 DI2 1 2002-02-27 TA8050F Pin Description Pin No. 1 3 FIN 8 9 15 16 2, 4~7 10~14 17~20 Symbol VCC GND DI1 DI2 M (+) M (-) Description Power supply pin. This pin has a function to turn off the output when the applied voltage exceeds 27.5 V, thus protecting the IC and the load. Grounded 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 1.5 A. Diod...
