Manufacturer:TI Description:The MAX1978 operates from a single supply and provides bipolar 3A output by biasing the TEC between the outputs of two synchronous buck regulators. True bipolar operation controls temperature without dead zones or other nonlin- earities at low load currents. The control system does not hunt when the set point is very close to the natural operating point, where only a small amount of heating or cooling is needed. An analog control signal precisely sets the TEC current. The MAX1979 provides unipolar output up to 6A. A chopper-stabilized instrumentation amplifier and a high- precision integrator amplifier are supplied to create a pro- portional-integral (PI) or proportional-integral-derivative (PID) controller. The instrumentation amplifier can interface to an external NTC or PTC thermistor, thermocouple, or semicon- ductor temperature sensor. Analog outputs are provided to monitor TEC temperature and current. In addition, separate overtemperature and undertemperature outputs indicate when the TEC temperature is out of range. An on-chip volt- age reference provides bias for a thermistor bridge. The MAX1978/MAX1979 are available in a low-profile 48-lead thin QFN-EP package and is specified over the -40C to +85C temperature range. The thermally enhanced QFN-EP package with exposed metal pad minimizes operating junction temperature. An evaluation kit is available to speed designs. |
