Haptic driver with I²C control for ERM and LRA actuators
The Texas Instruments DRV2625YFFT is a fully integrated haptic driver that combines control logic and a power stage in a single 9-DSBGA package. It drives both ERM (eccentric rotating mass) and LRA (linear resonant actuator) motors, making it a direct fit for haptic feedback in touchscreens, wearables, and control panels. Communication is handled over an I²C interface, so the host microcontroller programs drive waveforms, gain, and trigger modes without additional PWM pins.
Supply and temperature range — fits portable and industrial builds
The DRV2625YFFT operates from a single supply between 2.7 V and 5.5 V. Its junction temperature range of -40°C to 150°C suits equipment that sees hot environments or cold starts.
Output stage and actuator compatibility
A half-bridge output configuration (two outputs) drives the actuator directly. The driver supports both ERM and LRA motor types, so a single BOM line covers either actuator choice. No external MOSFETs or complex analog front-end are needed — the integrated power stage handles the drive current.
Package and mounting — small footprint for dense PCBs
Housed in a 9-bump DSBGA, the DRV2625YFFT is a surface-mount device that saves board area compared to a QFN or TSSOP haptic driver. Tape & Reel and Cut Tape options are available.
Lifecycle and compliance
No end-of-life notice or last-time-buy window is indicated, so it remains a safe choice for new designs and production ramps.
