Evaluation Board For Driver For DC Motors And Linear Vibrators With Ultra-Fast Turn-On
The is an evaluation module for evaluating DRV8601 device. The DRV8601 is a general purpose single supply haptics driver designed 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 100µs, the DRV8601 is an excellent haptics driver for use in mobile phones and other portable electronic devices. The evaluation module is easy to use and operate and is designed to interface with different haptics actuators in the market both ERMs and LRAs. The DRV8601 evaluation module can be operated in three configurations to yield flexibility to the haptics systems design.

This device has limited built in ESD protection. The leads should be shorted together or device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
This EVM should be operated within the input voltage range of 2.5V to 5V and the output voltage range of 0V to 5.5V. Exceeding the specified input range may cause damage to the EVM.
