BU64982GWZ-TR

Audio Special Purpose Overview

The BU64982GWZ-TR is a unidirectional voice coil motor (VCM) driver manufactured by Rohm Semiconductor. Designed primarily for camera auto-focus applications, it operates within a supply voltage range of 2.5V to 3.6V and supports an operating temperature range from -25°C to +85°C. The device features a 2-wire serial interface (I2C compatible) and is housed in a UCSP25L1-6 package (also referred to as UCSP30L1A in some contexts, but officially UCSP25L1-6 per datasheet). It is supplied in Tape & Reel or Cut Tape formats.

Audio Special Purpose Feature Summary

• Unidirectional VCM driver architecture
• 2-Wire Serial Interface (I2C compatible)
• 2.5V to 3.6V supply voltage operation
• UCSP25L1-6 (6-pin CSP) package
• Output current: 100 mA / 125 mA
• Operating frequency up to 2 MHz

Audio Special Purpose Applications

• Camera Auto-Focus (VCM) control
• Mobile phone cameras
• Webcams
• Digital audio interfacing (as secondary application)

Audio Special Purpose Procurement Notes

This component is marked as 'End of Life' (EOL) by the manufacturer. Procurement should be limited to existing stock only, with awareness that future availability is not guaranteed. Verify lot dates and storage conditions carefully due to EOL status.

Audio Special Purpose Selection Notes

Select this component when unidirectional drive capability is sufficient for the application, as opposed to bidirectional variants like the BU64985. Verify that the 2.5V to 3.6V supply range is compatible with the system power rails. Note that while often associated with digital audio interfaces in older descriptions, its primary modern application is VCM driving for autofocus systems.
