TA8050AK
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8050AK
1.5A MOTOR DRIVER WITH BRAKE FUNCTION
The TA8050AK is a 1.5A bi-directional DC motor driver and it
can switch forward, reverse, stop and brake mode with input DI1
and DI2. Protective functions are built in to protect IC and load
from destruction caused of over stress.
FEATURES
l Bi-directional DC Motor Driver
