MP8833 1.5 A Thermoelectric Cooler Controller

Monolithic Power Systems monolithic thermoelectric cooler controller has built-in internal power MOSFETs

Monolithic Power Systems introduces the MP8833, a monolithic thermoelectric cooler controller with built-in internal power MOSFETs. It achieves 1.5 A of continuous output current from a 2.7 V to 5.5 V 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 400 kHz 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 (2 mm x 3 mm) package for a minimum solution size.
