Overview: HY5640 TEC Controller Subminiature Controller for Thermoelectric Coolers The HY5640 is a subminiature temperature controller for thermoelectric coolers (TEC). This device is intended for “heat or cool” fixed temperature applications where front panel controls and digital readouts are not required. The HY5640 uses a thermistor bridge to precisely measure and regulate the temperature of a device affixed to a TEC. With proper heat sinking, the power stage of this device will deliver up to +/- 2 Amperes of current to a TEC. This controller was designed for single power suppply operation down to +5V. In addition, the device can be operated with dual supplies where VS can be as low as +3V and VDD as low as +5V. TEC Controllers Maximum ratings: Rating Supply Voltage 1 (Voltage on Pin 8) Supply Voltage 2 (Voltage on Pin 10) Current Sink (Heat and Cool Cycle) Maximum Power Dissipation Operating Temperature (Case) Storage Temperature Symbol V DD VS Is PMAX T MAX/MIN TSTG Value +20 +12 2.

of the HY5640 Pin Outs • Temperature Set Resistor Rs (Pin 1 to Pin 7) The temperature set resistor for the HY5640 controls the temperature at which the TEC will operate.
When the circuit has stabilized, the resistance of the thermistor will be equal to that of the set resistor Rs.
For example, if a Dale 10kΩ thermistor is used as the temperature sensing device, a set resistor of approximately 56KΩ will set an operating temperature of –10°C.
