Overview
The BU24036MWV-E2 is a microstepping lens driver manufactured by ROHM Semiconductor, designed for motor and motion control applications. It operates within a load voltage range of 1.62 V to 3.6 V and features six output channels capable of delivering up to 200 mA per channel. The device supports an operating frequency between 1 MHz and 28 MHz, with a maximum power dissipation of 2.6 W. It functions within a temperature range of -20°C to +85°C and utilizes a UQFN-40 surface-mount package.
Feature Summary
- Supports u-step lens driving functionality for precise motion control
- Integrates six independent output channels for multi-coil actuation
- Operates on low supply voltages suitable for portable devices
Applications
- Camera module lens positioning systems
- Optical zoom mechanism drivers
- Autofocus actuator control circuits
Procurement Notes
Verify the specific suffix E2 against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Confirm that the UQFN-40 package dimensions match your PCB footprint requirements. Ensure the input signal levels are compatible with the 1.62 V to 3.6 V operating range before integration into the final design.
Selection Notes
Select this component when designing compact optical systems requiring precise microstepping control within a low-voltage environment. The six-channel output allows for complex coil driving patterns necessary for smooth lens movement. Consider the thermal performance given the 2.6 W power dissipation limit in confined spaces typical of mobile camera modules.
Part Context
This part belongs to ROHM's series of dedicated lens drivers optimized for consumer electronics. It addresses the need for high-resolution positioning in small form-factor cameras. The integration of multiple outputs in a single UQFN package reduces board space compared to discrete solutions or fewer-channel alternatives.
Replacement Considerations
Check the BU24036MWV datasheet for direct pin-to-pin replacements within the same family. Verify if alternative ROHM lens drivers offer higher current ratings or different step resolutions if system requirements change.
