DA7282-00V42

Overview

The DA7282-00V42 is an ultra-low power haptic driver IC designed for ERM and LRA actuators. It operates on a supply voltage of 2.8V to 5.5V with a maximum output current of 500mA. The device features a standby current consumption of 5nA and supports frequency tracking up to 300Hz. It utilizes an I2C interface and is available in a 12-WLCSP package measuring 1.35x1.75mm.

Feature Summary

• Ultra-low power standby mode reduces system drain
• Wideband LRA driver supports resonant modes up to 1kHz
• Continuous resonance frequency tracking ensures consistent feedback
• Low-latency direct drive enables rapid haptic response

Applications

• Smartphones
• Gaming devices
• Wearables
• Portable computing systems

Procurement Notes

Verify the specific suffix V42 indicates the WLCSP packaging configuration as documented. Confirm RoHS compliance status through official Renesas documentation before integration. Ensure the I2C address settings align with system requirements, noting that this model differs from variants with multiple address capabilities. Check lead times as production cycles may vary.

Selection Notes

Select the DA7282-00V42 when ultra-low standby current is critical for battery life. Choose this part over the DA7281 if multiple I2C addresses are not required. Consider the WLCSP package size constraints against board space availability. Verify compatibility with Linux or C-like drivers for software implementation.

Part Context

This component belongs to the DA7282 series of haptic drivers. It distinguishes itself from the DA7280 and DA7281 by offering full standby mode capability. The series targets applications requiring complex touch effects with minimal power impact. It serves as a specialized solution within Renesas' motor and motion controller portfolio.
