DESCRIPTION
The DRV8601 is a single-supply haptic driver that is
optimized to drive a DC motor (also known as
Eccentric Rotating Mass or ERM in haptics
terminology) or a linear vibrator (also known as
Linear Resonant Actuator or LRA in haptics
terminology) using a single-ended PWM input signal.
With a fast turn-on time of 100 µs, the DRV8601 is an
excellent haptic driver for use in 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 control of both DC motors and
linear vibrators.
With a typical quiescent current of 1.7 mA and a
shutdown current of 10 nA, the DRV8601 is ideal for
portable applications. The DRV8601 has thermal and
output short-circuit protection to prevent the device
from being damaged during fault conditions.
