Remote Diode Thermal Switches
Requiring no external components, the MAX6511, MAX6512, and MAX6513 are factory-programmed to temperature thresholds from 45°C to +125°C in 5°C increments. Trip point accuracy is 0.5°C (typical) and ۭ°C (maximum) over the temperature range +45°C to +100°C and 5°C over the temperature range +100°C to +125°C. Hysteresis is pin-selectable to 5°C or to 10°C. The MAX6511 is a CMOS output (active low), MAX6512 is an open-drain output, and the MAX6513 is a CMOS output (active high).
These devices require less than 600 μA supply current and can operate from a supply voltage ranging from +2.7 V to +5.5 V. With their small size, these SOT23-6 devices are ideal for use in portable equipment and space constrained environments.
