The MAX6501 and MAX6502 are SOT-23 temperature switches requiring no external components, with design simplified through factory-preset temperature thresholds. Multiple factory-calibrated trip points are available. Pin-selectable hysteresis of +2°C or +10°C provides additional design flexibility. These devices typically consume only 17 μA and operate over the full -55°C to +125°C temperature range, with accuracy of ±0.5°C (typical) and ±4°C (maximum).

The MAX6501 features an open-drain, active-low output for microprocessor reset control. The MAX6502 features a CMOS, active-high output designed to drive logic-level MOSFETs for turning on fans or heating elements.

The MAX6501/6502 are intended for over-temperature monitoring (+45°C to +115°C). These devices assert a logic signal when temperature exceeds the threshold.

The MAX6501 and MAX6502 offer five standard temperature thresholds. Housed in a 5-pin SOT-23A package, these devices are ideal for applications requiring high integration, small size, low power consumption, and low-cost mounting.
