DA7283 is a linear resonant actuator (LRA) haptic

driver offering automatic closed-loop LRA resonant

frequency tracking. The feature guarantees

consistency across LRA production tolerances,

operating temperature, aging, and mechanical

coupling. DA7283 does not require any programming

to drive LRA motors within its supported range and

will automatically lock to the correct LRA resonant

frequency without any actuator information being

provided to the device.

The differential output drive architecture and

continuous actuator motion sensing enable efficient

playback. Featuring three low-latency (0.75 ms)

wake-up on general purpose input (GPI) sequence

triggers, DA7283 automatically returns to a low

quiescent current state (typically 0.68 µA) between

playbacks. In OFF mode the device consumes only 5

nA, making it the appropriate choice for low power

and long standby applications.

Three different types of haptic feedback effects can

be triggered via the GPIs. Time domain control of

these GPIs allows complex haptic effects playback

capability at two different drive levels without the

need for another digital interface to the device. This

feature makes DA7283 perfectly suited for products

that require unconditional haptic feedback like

security applications or industrial products and small

software footprint solutions like wearables or home

automation.
