The MAX1978/MAX1979 single-chip thermal electric controllers (TEC) from Maxim Integrated Products Inc. are claimed to be the world's smallest, occupying a 7-by-7mm footprint and encased in QFN packages.

Designed for use in optical modules and networks, the ICs integrate temperature-control circuitry, power MOSFETs, and protection and monitoring circuits. They control TEC current, instead of the TEC voltage, to eliminate surge currents in the TEC and improve system reliability.

A low-drift chopper stabilized error amplifier allows 10.0010C temperature set-point stability. Built-in current and temperature monitors and under/overtemperature alarms reduce external components.

The MAX1978 is rated at 13A bidirectional output current, while the MAX1979 is rated at 6A unidirectional output current. Both are rated at -400C to 850C.
