MP5491GC-0000-Z

Overview

The MP5491GC-0000-Z is a quad-channel laser diode current source IC designed for optical modules. It integrates four high-accuracy current sources to drive laser diodes. The device operates on a supply voltage range of 2.7 V to 5.5 V and supports an I2C interface for control. It functions within a temperature range of -40°C to +125°C. The component is housed in a 36-WLCSP package with dimensions of 3x4.25 mm, suitable for surface mount applications.

Feature Summary

• Integrates four independent high-accuracy current sources specifically optimized for laser diode driving
• Supports digital configuration via standard I2C communication interface
• Operates reliably across extended industrial temperature ranges up to 125°C

Applications

• Optical sensor modules
• Laser diode driver circuits
• Fiber optic communication transceivers

Procurement Notes

Verify the specific suffix Z against the manufacturer's latest documentation to confirm tape and reel packaging specifications. Ensure the design-in process accounts for the 36-WLCSP thermal requirements and I2C address configurations. Cross-reference the exact part number with official MPS distributors to avoid counterfeit components and confirm RoHS compliance status.

Selection Notes

Select this component when a compact solution for multi-channel laser control is required. The integrated nature reduces external component count compared to discrete designs. Consider the WLCSP footprint constraints during PCB layout. Verify that the system power supply remains within the 2.7 V to 5.5 V operating window for stable performance.

Part Context

This part belongs to the Monolithic Power Systems MP5491 series, specialized for optical interconnect applications. It serves as a dedicated driver for managing multiple laser channels within tight spatial constraints. The series targets high-density optical module designs where precision current regulation is critical for signal integrity.

Replacement Considerations
