Haptic driver with I²C — what it is and where it fits
The Texas Instruments DRV2625YFFR is a fully integrated haptic driver combining control logic and power stage in a single 9-DSBGA package. It communicates over an I²C bus and drives both ERM (eccentric rotating mass) and LRA (linear resonant actuator) motors, making it a direct fit for touch-feedback modules in smartphones, wearables, game controllers, and industrial HMI panels. The half-bridge output configuration drives one actuator differentially, so a single part covers one haptic channel per device.
Supply range and thermal headroom
Both the load supply and the logic supply share a common 2.7 V to 5.5 V range. The junction temperature rating of -40°C to 150°C is wide enough for automotive cabin and under-hood environments.
Lifecycle and sourcing
Status is Active — no end-of-life notice, no last-time-buy window. ROHS3 compliant. TI continues to manufacture this part for new designs. No second-source alternate is listed in the official record, so dual-sourcing would require a pin-compatible design review with a different driver IC.
