1.5A Thermoelectric Cooler Controller with Integrated MOSFETs
The MP8833 from Monolithic Power Systems, Inc. is a monolithic thermoelectric cooler controller with internal power MOSFETs. It achieves 1.5A continuous output current from a 2.7V-to-5.5V input voltage with TEC voltage range. The TEC voltage is linearly controlled by an analog voltage.
The features such as TEC voltage/current limit, can be controlled fly through a 3.4Mbps I2C serial interface. This results in a minimum of external components. Combined with a QFN-16 (2mm x 3mm) package, the solution size is also minimized.
Full protection features include internal soft start, over current/voltage protection and over temperature protection.
The MP8833 is designed for TEC device applications such as an optical laser diode, fiber communication network.
