DA7280-00V42

Overview

The DA7280-00V42 is a low-power haptic driver IC designed for LRA and ERM actuators. It operates within a supply voltage range of 2.8 V to 5.5 V and delivers an output current of 250 mA. The device functions at frequencies between 25 Hz and 1 kHz, with a typical operating supply current of 800 uA. It supports an operational temperature range from -40°C to +85°C and utilizes a WLCSP-12 package for surface-mount installation.

Feature Summary

• Integrated full control and power stage for linear resonant and eccentric rotating mass actuators
• I2C programmable interface for configuration and waveform management
• Supports automatic resonant frequency tracking for LRA applications

Applications

• Smartphones and mobile devices
• Wearable electronics
• Industrial human-machine interfaces

Procurement Notes

Verify the specific suffix '00V42' against official Renesas documentation to confirm exact packaging and reel specifications. Confirm RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer prior to ordering.

Selection Notes

Select this component when a compact WLCSP footprint is required for haptic feedback systems. Ensure the application demands a single-channel driver with I2C control. Verify that the actuator type matches the supported LRA or ERM categories and that the system voltage aligns with the 2.8 V to 5.5 V input range.

Part Context

This part belongs to the DA7280 series of high-definition haptic drivers manufactured by Renesas Electronics. The series focuses on providing precise tactile feedback solutions for portable and industrial devices through integrated digital control architectures.

Replacement Considerations

Consult official substitution lists for variants such as DA7280-00FVC or other packages within the same family. Cross-reference pinouts and electrical characteristics before replacing.
