Overview
The MP8833GD-0000-P is a monolithic thermoelectric cooler (TEC) controller from Monolithic Power Systems, featuring built-in internal power MOSFETs. It delivers up to 1.5A of continuous output current within an input voltage range of 2.7V to 5.5V. The device operates with a default switching frequency of 1MHz and includes an I2C serial interface for controlling TEC voltage and current limits. It provides 1% accuracy for the 2.5V reference and incorporates protection features such as over-current, over-voltage, and over-temperature protection. The component is housed in a compact QFN-16 package measuring 2mm x 3mm.
Feature Summary
- Monolithic integration of TEC controller with internal power MOSFETs
- Analog linear control of TEC voltage combined with digital I2C configuration
- Comprehensive protection suite including soft start, OCP, OVP, and OTP
- Compact QFN-16 package design for minimal solution footprint
Applications
- Optical laser diode temperature stabilization

Procurement Notes
Verify the specific suffix designation when ordering, as variants exist with different packaging or tape-and-reel configurations. Confirm that the QFN-16 package dimensions align with your PCB layout requirements. Ensure compatibility with the 2.7V to 5.5V input supply range for your system design. Cross-reference the active part numbers listed in official documentation to confirm availability and exact specifications before finalizing procurement.
Selection Notes
Select this component for applications requiring precise TEC control with integrated power stages. The 1.5A output capability suits moderate thermal loads. Consider the 1MHz switching frequency for balancing efficiency and external component size. The I2C interface allows for dynamic adjustment of cooling parameters. Verify that the operating temperature range of -40°C to +125°C meets environmental demands.
Part Context
