Key Document


The DRV8662/DRV2665/DRV2667 Design Equation document assists the user in the design phase by calculating the driver hardware configuration based off of user-defined input parameters. The DRV8662/2665/2667 is a piezo haptic driver with integrated 105 V boost switch, integrated power diode, and integrated fully-differential amplifier.  These versatile devices are capable of driving both high-voltage and low-voltage piezo haptic actuators.  The DRV2665/7 adds in a digital front end via an I2C compatible bus that relieves the costly processor burden of PWM generation or additional analog channel requirements in the host system.  Finally, the DRV2667 has an internal waveform memory that further relieves the host processor of haptic generation duties.
