BU64292GWZ-TR

Audio Special Purpose Overview

The BU64292GWZ-TR is a unidirectional voice coil motor (VCM) driver manufactured by ROHM Semiconductor, designed specifically for camera auto-focus applications. It operates on a supply voltage range of 2.5 V to 3.6 V and supports an operating temperature from -25°C to +85°C. The device features a 2-wire serial interface compatible with I²C standards. It provides output currents of 100 mA and 125 mA, with a maximum power dissipation of 270 mW. The component is housed in a UCSP25L1-6 package (6-XFBGA/CSPBGA) and is available in Tape & Reel or Cut Tape formats.

Audio Special Purpose Procurement Notes

This component is listed as 'End of Life' (EOL) / 'Last Time Buy'. Manufacturers may discontinue production. Verify availability and lead times carefully before procurement. Confirm the specific package variant (UCSP25L1-6) and interface compatibility with the target system design. Ensure that the 2.5 V to 3.6 V supply voltage range aligns with the application requirements.

Audio Special Purpose Selection Notes

Select this component for applications requiring precise unidirectional current control for VCMs. Consider the 100 mA/125 mA output options based on the motor's current demands. Verify that the I²C address configuration meets the system's bus addressing needs. Check thermal performance within the specified -25°C to +85°C range.
