The TM200 is a fully integrated programmable thermal management unit that monitors, controls, and corrects analog circuitry across a wide temperature range. The TM200 is primarily intended for OCXO applications and includes a temperature sensor, internal Pierce oscillator & output stage, thermal controller, internal heater and data converters combined with a microcontroller (MCU) and memory structures. The TM200 controls and regulates the temperature environment of small enclosures by executing temperature stability and correction programs. The Pierce oscillator and output stage are designed to be flexible with a variety of oscillator and crystal configurations. The TM200 includes many programmable functionality options, and its software package makes it easy to configure and implement various crystal correction algorithms. It communicates via an I²C interface and is available in a 3mm x 3mm package or as die.
