3 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.
