SLOS824C – DECEMBER 2012 – REVISED MARCH 2018
DRV2604 Haptic Driver for ERM and LRA With Internal Memory
and Smart-Loop Architecture
1 Features
1 Flexible Haptic/Vibra Driver
– LRA (Linear Resonance Actuator)
– ERM (Eccentric Rotating Mass)
• I2C Controlled Digital Playback Engine
– Internal RAM for Waveform Storage
– Real-Time Playback Mode through I2C
• Smart-Loop Architecture(1)
– Automatic Overdrive/Braking (ERM/LRA)
– Automatic Resonance Tracking (LRA)
– Automatic Actuator Diagnostic (ERM/LRA)
– Automatic Level Calibration (ERM/LRA)
• Immersion TouchSense® 3000 Compatible
• Optional PWM Input with 0% to 100% Duty Cycle
Control Range
• Optional Analog Input Control
• Optional Hardware Trigger Pin
• Efficient Output Drive
• Fast Startup Time
• Constant Acceleration Over Supply Voltage
• 1.8-V Compatible, VDD-Tolerant Digital Pins
(1) Patent pending control algorithm
The DRV2604 device includes enough integrated
RAM to allow the user to pre-load over 100
customized waveforms. These waveforms can be
instantly played back through I2C or optionally
triggered through a hardware trigger pin. Additionally,
the real-time playback mode allows the host
processor to bypass the library playback engine and
play waveforms directly from the host through I2C.
The DRV2604 device also contains a smart-loop
architecture, which allows effortless auto resonant
drive for LRA as well as feedback-optimized ERM
drive. This feedback gives automatic overdrive and
braking, which creates a simplified input waveform
paradigm as well as reliable motor control and
consistent motor performance.
The DRV2604 device features a trinary-modulated
output stage, providing greater efficiency than linear-
based output drivers. The 9-ball WCSP footprint,
flexible operation, and low component count make
the DRV2604 device the ideal choice for portable and
touch-enabled vibratory and haptic applications.

3 Description
The DRV2604 device is designed to provide
extremely flexible haptic control of ERM and LRA
actuators over a shared I2C compatible bus. This
control relieves the host processor from ever
generating pulse-width modulated (PWM) drive
signals, saving both costly timer interrupts and
