DA7283-01FVC

Overview

The DA7283-01FVC is an ultra-low power haptic driver designed for Linear Resonant Actuators (LRA) and Eccentric Rotating Mass (ERM) motors. It features automatic closed-loop LRA resonant frequency tracking up to 1kHz, supporting both on-resonance and off-resonance drive sequences. The device integrates full control and power stages with a bipolar motor driver interface via I2C. It operates within a voltage range of 2.8V to 5.5V and supports output currents up to 500mA. Packaged in a compact 12-VQFN (3x3mm) format, it functions across a temperature range of -40°C to 85°C.

Feature Summary

• Automatic closed-loop LRA resonant frequency tracking
• Supports custom drive sequences at up to 1kHz
• Integrated full control and power stage
• Three GPI pins for triggering clicks and complex patterns

Applications

• Mobile devices requiring haptic feedback
• Wearable technology with vibration alerts
• Industrial equipment needing tactile indicators
• Gaming controllers with force feedback

Procurement Notes

Verify the specific suffix '01' against the manufacturer's latest datasheet to confirm pinout and functional compatibility with existing designs. Ensure the 12-VQFN package dimensions match the PCB footprint exactly. Confirm that the I2C address configuration meets system requirements before finalizing procurement orders.

Selection Notes

Select this component when automatic resonant frequency tracking is required for LRAs to maintain consistent haptic performance. It is suitable for applications demanding low power consumption and integrated power stages without external programming. Compare output current capabilities against actuator specifications to ensure adequate drive strength for the intended mechanical load.

Part Context

This part belongs to the Renesas DA728x family of haptic drivers, which includes variants like the DA7280, DA7281, and DA7282. These components share similar interfaces and packaging but differ in output current ratings and specific feature sets. The DA7283 series is optimized for high-performance LRA applications with advanced tracking capabilities.
