The MP8833A 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 MP8833A 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 MP8833A is available in a QFN-16 (2mmx3mm) package for a tiny solution size.
