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 analogue 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 fibre 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. Typical applications include optical laser diode modules, fibre communication networks and systems with TEC temperature control.
