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.
