DRV8601ZQVEVM ERM/LRA Driver Evaluation Module
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. All
components and the evaluation module are Pb-free. The evaluation module (EVM) consists of a
DRV8601ZQV device and all necessary components to evaluate it.
