SGM41299C Datasheet 3a Thermoelectric Cooler Driver

Manufacturer: SG Micro

Overview: SGM41299C 3A Thermoelectric Cooler (TEC) Driver GENERAL.

General Description

The SGM41299C 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 reference voltage 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.
  • Single-Ended to Differential Driver with Low RDSON MOSFETs inside.
  • TEC Voltage and Current Monitoring.
  • No External Sense Resistor Required.
  • Independent Heating and Cooling Current/Voltage Limits Programming.
  • PWM Driver Switching Frequency: 2.0MHz (TYP).
  • Two Rail-to-Rail, Zero-Drift Chopper Amplifiers.
  • Compatible with RTD or NTC Thermal Sensors.
  • 2.5V Output Reference Voltage.
  • Temperature Lock Indicato.
