Monolithic Power Systems (MPS) MP8833x Thermoelectric Cooler Controllers feature built-in internal power MOSFETs and achieves 1.5A continuous output current. These controllers include TEC current monitor, external SYNC function, and EN/SD for power sequencing. The MP8833x cooler controllers provide full protection that includes internal soft-start, Over-Current Protection (OCP), Over Voltage Protection (OVP), and Over-Temperature Protection (OTP). These controllers operate at -40°C to 125°C temperature range and 2.7V to 5.5V input voltage range. The MP8833x controllers offer 1MHz switching frequency and 2.27W QFN continuous power dissipation. Typical applications include optical laser diode modules, fiber communication networks, and systems with TEC temperature control.
