Control is through a parallel or PWM interface, giving the host MCU flexibility to generate custom haptic waveforms or use a simple PWM duty cycle for fixed-intensity vibration. The Power MOSFET output stage handles the actuator current directly without external FETs.
It is ROHS3 compliant.
Yes, the DRV2603RUNR supports both eccentric rotating mass (ERM) and linear resonant actuator (LRA) motor types.
The DRV2603 is a simpler driver with parallel/PWM control, while the DRV2605 adds an I2C interface and built-in haptic waveform library. For designs needing custom waveform generation from an MCU, the DRV2603's parallel/PWM interface is sufficient.
The DRV2603RUNR is a dedicated haptic driver for ERM/LRA. Higher-current alternatives like the DRV8876RGTR (3.5 A, brushed DC) or DRV8424PWPR (2.5 A, stepper) serve different motor types and are not direct haptic replacements.
