Low Voltage, Resistor Programmable Thermostatic Switch

The AD22105 is a solid state thermostatic Switch Requiring only one external programming resistor, the AD22105 CAN be set to Switch accurately at any temperature in the wide operating range of -40C to +150C. Using a novel circuit architecture, the AD22105 asserts an Open Collector output when the ambient temperature exceeds the user-programmed setpoint temperature. The AD22105 has approximately 4C of hysteresis which prevents rapid thermal on/off cycling.
The AD22105 is designed to operate on a single power supply voltage from +2.7 V to +7.0 V facilitating operation in battery powered applications as well as in Industrial Control systems. Because of low power dissipation (230 W @ 3.3 V), self-heating errors are minimized and battery life is maximized.
An optional internal 200 k(ohm) pull-up resistor is included to facilitate driving light loads such as CMOS inputs.
Alternatively, a low power LED indicator may be driven directly.
