BU64562GWZ-E2

Overview

The BU64562GWZ-E2 is a piezo actuator driver manufactured by ROHM Semiconductor, designed for haptic feedback applications. It features two half-bridge outputs capable of delivering up to 400 mA output current. The device operates on a supply voltage range of 2.3 V to 4.8 V with a typical quiescent current of 1.8 mA. It supports I2C interface communication at frequencies up to 400 kHz. The component functions within an operating temperature range of -25°C to +85°C and is housed in an 8-pin UCSP30L1-8 surface-mount package.

Feature Summary

• Integrates dual half-bridge drivers specifically optimized for piezoelectric actuators
• Enables precise control via standard I2C digital interface
• Designed for low power consumption suitable for portable devices

Applications

• Haptic feedback systems in mobile devices
• Piezo actuator driving for vibration motors
• Smartphone and wearable technology interfaces

Procurement Notes

Verify the End-of-Life (EOL) status before finalizing designs, as the manufacturer indicates this part is subject to obsolescence. Confirm that the UCSP30L1-8 package dimensions align with your PCB footprint requirements. Ensure compatibility with the 2.3V to 4.8V supply rail and I2C bus voltage levels used in your target system architecture.

Selection Notes

Select this component when designing compact haptic solutions requiring dual-channel piezo drive capability. It is appropriate for systems where space constraints necessitate the small UCSP30L1-8 package. Consider its 400 mA peak output and I2C controllability if digital regulation of vibration intensity is required. Verify thermal dissipation capabilities within the specified -25°C to +85°C range for your specific enclosure.

Part Context

This part belongs to ROHM's PMIC Motor Driver and Haptic Drivers product line. It is categorized under Piezo Actuator Drivers, distinct from general motor controllers or linear regulators. The E2 suffix typically denotes environmental compliance variations within the same functional family.

Replacement Considerations

Due to the confirmed End-of-Life status, direct substitutes should be sought from ROHM's current haptic driver portfolio. Evaluate newer packages or updated series for pin-compatible alternatives that maintain I2C control and similar output current specifications.
