FEATURES  
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.

High Current Output: 400 mA  
Wide Supply Voltage (2.5 V to 5.5 V) for Direct  
Battery Operation  
Low Quiescent Current: 1.7 mA Typical  
Fast Startup Time: 100 µs  
Low Shutdown Current: 10 nA  
Output Short-Circuit Protection  
Thermal Protection  
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.  
Enable Pin is 1.8 V Compatible  
Available Package Options

APPLICATIONS  
Mobile Phones  
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.
