DA7281-00FVC

Overview

The DA7281-00FVC is a low-power haptic driver IC designed for ERM and LRA actuators. It features an integrated control and power stage with I2C interface. The device supports wideband LRA driving from 25Hz to 1kHz, including resonant mode tracking up to 300Hz. It offers ultra-low idle current consumption of 360nA with full I2C control and memory retention. The component operates within a supply voltage range of 2.8V to 5.5V and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Supports custom waveform sequences and on-the-fly diagnostics for complex touch effects
• Enables multiple devices on the same I2C bus using configurable address pins
• Provides low-latency direct drive triggering from deep sleep states

Applications

• Smartphones
• Gaming peripherals
• Wearable devices

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and reel specifications. Ensure compatibility with system I2C addressing requirements, as this variant utilizes trigger pins for address configuration. Confirm moisture sensitivity level handling procedures during assembly to prevent damage.

Selection Notes

Select this component when multiple haptic drivers are required on a single I2C bus due to its unique address pin configuration. Choose this part for applications demanding ultra-low standby power consumption while maintaining immediate wake-up responsiveness. Verify actuator type compatibility, as it supports both ERM and wideband LRA technologies.

Part Context

This part belongs to the DA7281 series of haptic drivers. It differs from related models like the DA7280 and DA7282 by repurposing trigger input pins as I2C address lines. This design allows up to four units to operate simultaneously on one bus without external address selection hardware.
