DescriptionThe DRV8601isa single-supply haptic driver thatis
optimized to drivea DC motor (also known as
Eccentric Rotating Mass or ERM in haptics
terminology) ora linear vibrator (also known as
Linear Resonant Actuator or LRA in haptics
terminology) usinga single-ended PWM input signal.
Witha fast turn-on timeof 100 µs, the DRV8601isan
excellent haptic driver for usein mobile phones and
other portable electronic devices.
The DRV8601 drives up to 400 mA from a
3.3-V supply. Near rail-to-rail output swing under load
ensures sufficient voltage drive for most DC motors.
Differential output drive allows the polarity of the
voltage across the output to be reversed quickly,
thereby enabling motor speed control in both
clockwise and counter-clockwise directions, allowing
quick motor stopping.A wide input voltage range
allows precise speed controlof both DC motors and
linear vibrators.
Witha typical quiescent current of 1.7 mA anda
shutdown currentof 10 nA, the DRV8601is ideal for
portable applications. The DRV8601 has thermal and
output short-circuit protectionto prevent the device
from being damaged during fault conditions.
