DN1220 - SUBMINIATURE THERMOELECTRIC COOLER CONTROLLER

General Description

The DN1220 is a subminiature Bipolar Temperature Controller for Thermoelectric Coolers (TEC) used in fixed temperature OEM applications.

The device is designed to operate with a Negative Temperature Coefficient (NTC) thermistor that senses the temperature of the object attached to the TEC.

Key Features

  • Proportional and Integral Control.
  • Gain and Integrator Time Constants set with Single Resistors. No External Integrator Capacitor Needed.
  • Single Power Supply Operation. +5 to +12 Volts D. C.
  • ± 2 Ampere Drive Capability.
  • Independent Cool and Heat Current Limit Adjustments.
  • Temperature Stability Better Than 0.01°C.
  • Small Size Hybrid Circuit Construction Pin Configuration INT OUT RTC IN.

™ DATA SHEET DN1220 SUBMINIATURE THERMOELECTRIC COOLER CONTROLLER General Description The DN1220 is a subminiature Bipolar Temperature Controller for Thermoelectric Coolers (TEC) used in fixed temperature OEM applications. The device is designed to operate with a Negative Temperature Coefficient (NTC) thermistor that senses the temperature of the object attached to the TEC. Temperature is set with a user selected resistor. Temperature stability of 0.01°C is achieved by the linear Proportional Integral (PI) control loop of the DN1220. Proportional gain and integrator time constants are set independently with resistors. No external integrator capacitor is needed. These parameters can be optimized to minimize temperature overshoot and stability.
