The compact design of the WTC3243HB Temperature Controller achieves 0.0009°C temperature stability. This adaptation of the standard WTC3243 operates from 3.6 V, Lithium-Ion batteries. The sensor range is limited to 1.6 V (with 3.3 V power supply). Do not operate over 8 V input.
Its package can be integrated with a heatsink WHS302, thermal washer WTW002, and fans WXC303 (5 V) or WXC304 (12 V) for easy prototyping. The linear, PI control loop offers maximum stability while the bipolar current source has been designed for higher efficiency. The WTC3243HB drives up to 2.2 A for either Thermoelectrics (bipolar) or Resistive Heaters (unipolar).
The WTC3243 temperature controller is easily configured for any design. A circuit calculator tool speeds selection of external component values (see Design Tools tab). Virtually any type of temperature sensor can be used with it and a built in sensor bias current source simplifies use with resistive temperature sensors. The Proportional Gain (P) and Integrator Time Constant (I) are set by external resistors and can be modified to optimize temperature overshoot and stability.
Other features offer added flexibility. Independent heat and cool current limits are set by single resistors. An onboard reference voltage simplifies potentiometer control of the temperature setpoint. You can also choose to operate remotely with an external setpoint voltage. Monitor actual sensor voltage at pin 9.
The robust and reliable WTC3243HB is designed into handheld electro-optical systems, airborne instrumentation, and medical diagnostic equipment. The WTC is particularly suited to applications where temperature is scanned across ambient.
WTC3243 vs. WHY5640:
- The WTC3243 incorporates remote voltage control and temperature monitor. The WHY5640 does not.
- The WTC3243 supports AD590 and LM335.
- The WHY5640 requires external circuits to operate anything other than resistive sensors.
- Two or more WHY5640s can be used together for more output current.
NOTE: The WHY5640 and WTC3243 do NOT have the same pin configuration.
