19-1712; Rev 1; 4/00 Dual Trip SOT Temperature Switches General Description Features The MAX6505–MAX6508 temperature switches have dual ±0.5°C (typ) Threshold Accuracy Over Full logic outputs that assert when the die temperature cross- Temperature Range es their trip thresholds. Trip thresholds are factory pro- No External Components Required grammed to convenient temperatures in 5°C increments. Low Cost The MAX6505/MAX6506 have an ALARM output that 30µA (typ) Supply Current asserts when the temperature is above the factory-pro- grammed thresholds (available from -40°C to +125°C). Factory-Programmed Thresholds from -40°C to They also have a WARN output that asserts when the +125°C in 5°C Increments temperature is several degrees below the ALARM thresh- Open-Drain
