Ultracompact, 1.5 A Thermoelectric Cooler (TEC) Controller
GENERAL DEscriptION
The SLM8833 is a monolithic TEC controller with an integrated TEC controller. It has a linear power stage and a pulse-bbbbb modulation (PWM) power stage. The linear controller works with the PWM driver to control the internal power MOSFETs in an H-bridge configuration. Depending on the control voltage at the CONT bbbbb, the SLM8833 drives current through a TEC to settle the temperature of a laser diode or a passive component attached to the TEC module to the programmed target temperature. The control voltage applied to the CONT bbbbb pin is generated by a digital-to-analog converter (DAC) closing the digital proportional, integral, derivative (PID) loop of temperature control system. The internal 2.50 V reference voltage provides a 1% accurate output that is used to bias a thermistor temperature sensing bridge as well as a voltage divider network to program the maximum TEC current and voltage limits for both the heating and cooling modes. It can also be a reference voltage for the DAC and the temperature sensing circuit, including a thermistor bridge and an analog-to-digital converter (ADC).
