General Description

The SGM41299 is a monolithic thermoelectric cooling (TEC) thermostat driver device with two-stage feedback amplifier.

The device includes a differential driver (output) stage, an internal 2.5V output voltage reference and two zero-drift, rail-to-rail chopper amplifiers.

The first chopper amplifier biases the sensed temperature signal and another is an error amplifier for pensating the closed loop temperature control.

Key Features

  • High Efficiency Single Inductor Architecture.
  • Integrated Low RDSON MOSFETs for the TEC Controller.
  • TEC Voltage and Current Monitoring.
  • No External Sense Resistor Required.
  • Independent Heating and Cooling Current-Limit Settings Programmable Maximum TEC Voltage.
  • PWM Driver Switching Frequency: 2.0MHz (TYP).
  • Two Zero-Drift, Rail-to-Rail Chopper Amplifiers.
  • Compatible with NTC or RTD Thermal Sensors.
  • 2.50V Output Voltage Reference.
  • Temperature Lock.
