DA7280-00FV2

Overview

The DA7280-00FV2 is a low-power, wide-bandwidth haptic driver IC designed for high-definition tactile feedback. It supports both ERM and LRA actuators with resonant frequency tracking up to 300Hz. The device features an I²C interface, ultra-low idle current of 360nA, and low-latency trigger inputs. It operates within a voltage range of 2.5V to 5.5V and is housed in a QFN package.

Feature Summary

• Supports custom waveform sequences and on/off-resonance drive modes for complex touch effects
• Features continuous current drive monitoring for automatic resonance frequency tracking
• Provides ultra-low power consumption with standby current below 1μA and fast wake-up times
• Includes built-in diagnostics for open/short circuit detection and over-temperature protection

Applications

• Smartphones and mobile devices requiring HD haptic feedback
• Wearable electronics and personal medical devices
• Gaming controllers and industrial HMI interfaces
• Touch displays and portable computing systems

Procurement Notes

Verify the specific suffix '00FV2' against official Renesas documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with the target I²C bus configuration and actuator type (ERM or LRA). Confirm moisture sensitivity level requirements for surface mount assembly processes.

Selection Notes

Select this component when multiple haptic drivers are required on a single I²C bus, as other variants like DA7281 offer address pin flexibility. Choose based on the need for wide-bandwidth LRA support and low-latency response from deep sleep states. Evaluate thermal management needs given the integrated power stage capabilities.

Part Context

Part of the DA728x family of high-definition haptic drivers from Renesas. This series integrates control logic and power stages into a compact solution, replacing traditional discrete PWM drivers. It enables software-defined haptic experiences through programmable waveforms and real-time parameter adjustment via I²C.

Replacement Considerations

DA7280-00FVC offers alternative packaging options. DA7281 provides additional I²C address configurations. Verify pinout compatibility and register map alignment before substitution.
