General Description
DA7281 is a linear resonant actuator (LRA) and eccentric rotating mass (ERM) haptic driver offering automatic closed-loop LRA resonant frequency tracking.
The feature guarantees consistency across LRA production tolerances, operating temperature, aging, and mechanical coupling.
Key Features
- LRA or ERM drive capability.
- Up to four I2C addresses via two address pins.
- Automatic LRA resonant frequency tracking.
- Wideband LRA support.
- I2C and PWM input streaming.
- Low latency (0.75 ms) I2C/GPI wake-up from low power consumption IDLE state, IQ = 0.36 µA.
- No software requirements with embedded operation.
- Differential PWM output drive.
- Current driven system to deliver constant actuator power.
- Configurable EMI suppression.
- Ultra-low.
