75°C fixed trip — no software, no drift
The Maxim MAX6685AU75H is a dual temperature switch with a fixed switching temperature of 75°C. It monitors its own die temperature and asserts an active-high push-pull output when the temperature crosses that threshold. Accuracy is ±1.5°C, which gives you a clean guard band for thermal shutdown or fan control without needing a microcontroller or ADC.
Housed in an 8-µMAX package (3.00 mm × 3.00 mm body, 0.118" width), surface-mount only. The 8-TSSOP and 8-MSOP footprints are interchangeable for this package outline. No external components needed — just the supply bypass cap.
