With only one external programming resistor, the device can be set to switch at any temperature from -40C to +150C with +\/-2C maximum accuracy. When the ambient temperature exceeds the setpoint, the open-collector output asserts. The 4.1C typical hysteresis prevents rapid on\/off cycling. At 230uW power dissipation (3.3V), self-heating errors are minimized.","working_principle":"The AD22105 uses a silicon temperature sensor that generates a voltage proportional to the ambient temperature (PTAT). This voltage is compared against a reference set by the external RSET resistor. When the sensor voltage exceeds the setpoint threshold, the comparator drives the open-collector output stage active. The 4.1C hysteresis is built into the comparator to prevent oscillation near the trip point. The internal 200k pull-up resistor allows direct connection to CMOS inputs or low-power LEDs without external components.","pin_description":"
