I2C Bus Control up to 400 kHz  
Internal 100 Byte FIFO Interface  
Immersion TS5000 Compliant  
Optional Analog Inputs  
integrated fully-differential amplifier, and integrated  
digital front end. This versatile device is capable of  
driving both high-voltage and low-voltage piezo haptic  
actuators. The input signal can be driven as haptic  
packets over the I2C port or via the analog inputs.  
The DRV2665 digital interface is available via an I2C  
compatible bus. A digital interface relieves the costly  
processor burden of PWM generation or additional  
analog channel requirements in the host system. Any  
writes to the internal first-in, first-out buffer (FIFO) will  
automatically wake up the device and begin playing

Drives up to 150 nF at 150 VPP and 300 Hz  
Drives up to 330 nF at 100 VPP and 300 Hz  
Drives up to 680 nF at 50 VPP and 300 Hz  
Differential Output  
the waveform after the  
2 ms internal startup  
procedure. When the data flow stops or the FIFO  
under-runs, the DRV2665 will automatically enter a  
pop-less shutdown procedure.

Adjustable Boost Voltage  
Adjustable Boost Current Limit  
Integrated Power FET and Diode  
No Transformer Required  
The boost voltage is set using two external resistors,  
and the boost current limit is programmable via the  
REXT resistor. A typical start-up time of 2 ms makes  
the DRV2665 an ideal piezo driver for fast haptic  
responses. Thermal overload protection prevents the  
device from being damaged when overdriven.
