Overview
The DA7282-00FV2 is an ultra-low power haptic driver IC designed for ERM and LRA actuators. It features a full-integrated control and power stage with a half-bridge output configuration. The device supports I2C interface communication and operates within a supply voltage range of 2.8V to 5.5V. It delivers up to 500mA output current and functions in temperatures from -40°C to 85°C. The component is housed in a 12-VQFN package (3x3mm) with a 0.65mm pitch.
Feature Summary
- Provides wideband LRA driving capability from 25Hz to 1kHz with resonant mode support.
- Achieves ultra-low standby current consumption of 5nA to minimize battery drain.
- Supports continuous resonance frequency tracking up to 300Hz for complex touch effects.
- Enables low-latency direct drive response from standby state.
Applications
- Smartphones
- Gaming devices
- Wearables
- Portable computing systems
Procurement Notes
Verify the specific suffix FV2 corresponds to the QFN-12 package variant when sourcing. Confirm moisture sensitivity level requirements and reflow soldering profiles during assembly planning. Ensure I2C address configurations align with system design constraints. Validate that the 500mA output current meets actuator drive requirements for selected ERM or LRA components.
Selection Notes
Select this model for applications requiring minimal standby power consumption alongside high-fidelity haptic feedback. The integrated driver reduces external component count compared to discrete solutions. Consider the QFN package size for space-constrained mobile designs. Verify compatibility with Linux and C-like driver frameworks for software integration.
Part Context
This component belongs to the DA7282 series of haptic drivers from Renesas Electronics. It differs from related models like the DA7280 and DA7281 by offering a dedicated full standby mode with significantly reduced current draw. The series targets modern mobile and wearable electronics demanding extended battery life without compromising tactile performance.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-referencing with other Renesas haptic drivers based on package and electrical specifications.
