DRV8601ZQVEVM: ERM and LRA Haptic Driver, 400mA, 2.5 ~ 5.5V

Summary

The DRV8601 ERM/LRA driver evaluation module is a complete, low-power and ultra-fast turn-on driver for Eccentric Rotating Mass (ERM) and Linear Resonant Actuator (LRA) types of haptic actuators 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.

The evaluation module (EVM) consists of a DRV8601ZQV device and all necessary components to evaluate it.
