Product Description

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 fly through a 3.4Mbps I2C serial interface. This brings minimum external components. Combined with a QFN-16 (2mmx3mm) 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.
