TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8050F
1.5 A DC Motor Driver with Brake Function
TA8050F
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 : 1.5 A
· Four modes
: 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
