MP8833GD-0000-Z

Overview

The MP8833GD-0000-Z is a monolithic thermoelectric cooler controller from Monolithic Power Systems, designed for precision temperature regulation. It integrates internal power MOSFETs and operates within an input voltage range of 2.7V to 5.5V. The device delivers a maximum output current of 1.5A with a fixed switching frequency of 1MHz. It features a 16-PowerVFQFN package and supports I2C interface control. The component functions reliably across an operating temperature range of -40°C to +125°C (TJ) with a typical supply current of 1mA.

Feature Summary

• Integrates internal power MOSFETs for compact thermoelectric cooling solutions
• Supports digital control via I2C interface for precise parameter adjustment
• Includes shutdown functionality to minimize power consumption during idle states

Applications

• Precision temperature control for laser diodes
• Thermal management in optical communication modules
• Temperature stabilization for infrared sensors

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the QFN-16 package dimensions match your PCB footprint requirements. Ensure the design supports the required 1MHz switching frequency noise profile. Validate that the 2.7V to 5.5V input range aligns with your system power rails.

Selection Notes

Select this component when a compact, integrated solution for TEC driving is required without external high-side or low-side drivers. The 1.5A output capability suits moderate thermal loads. Consider the I2C interface if digital monitoring and control are necessary. The wide junction temperature range ensures reliability in demanding environments.

Part Context

This part belongs to the MP8833 series of thermoelectric cooler controllers. It is distinct from general-purpose buck regulators like the MP8880 due to its specialized integration for Peltier element drive. The 'GD' designation typically refers to the specific package and temperature grade configuration within the MPS portfolio.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided source material. Designers should consult official MPS documentation for pin-compatible alternatives or updated recommendations, as generic cross-references may not guarantee functional equivalence for specialized TEC controllers.
