The MP8833 is a monolithic thermoelectric cooler controller with built-in internal power MOSFETs. It achieves 1.5A of continuous output current from a 2.7V to 5.5V input voltage range with a thermoelectric cooler (TEC) voltage range. The TEC voltage is linearly controlled by the analog voltage.
Features such as TEC voltage and current limiting are controlled by the 400kHz I2C serial interface. The MP8833 is ideal for TEC device applications, such as optical laser diodes and fiber communication networks.
Full protection features include internal soft start, over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection (OTP).
The MP8833 is available in a QFN-16 (2mmx3mm) package for a minimum solution size.

EV8833-D-01B Evaluation Kit 1.5A Thermoelectric Cooler Controller Evaluation Demo Board
The MP8833 is a monolithic thermoelectric cooler controller with built-in 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 linear controlled by an analog voltage.
The features such as TEC voltage/current limit, can be controlled on-the fly through a 3.4Mbps I2C serial interface. This brings minimum external components. Combined with a QFN package, the minimum solution size is obtained.
Fully protection features includes internal soft start, over current/voltage protection and over temperature protection.
The MP8833 is ideal for TEC device application such as an optical laser diode, fiber communication network.
The EVKT-MP8833 is an evaluation kit for the MP8833, which is a monolithic thermoelectric cooler controller with built-in internal power MOSFETs.
Communication Interface Device USB to I2C/PMBus, included with product evaluation kit or can be purchased separately.
