1 / 8 page ________________General Description The MAX6501–MAX6504 low-cost, fully integrated tem- perature switches assert a logic signal when their die temperature crosses a factory-programmed threshold. Operating from a +2.7V to +5.5V supply, these devices feature two on-chip, temperature-dependent voltage references and a comparator. They are available with factory-trimmed temperature trip thresholds from -45°C to +115°C in 10°C increments, and are accurate to ±0.5°C (typ) or ±6°C (max). These devices require no external components and typically consume 30µA sup- ply current. Hysteresis is pin-selectable at +2°C or +10°C. The MAX6501/MAX6503 have an active-low, open-drain output intended to interface with a microprocessor (µP) reset input. The MAX6502/MAX6504 have an active- high, push-pull output intended to directly drive fan- control logic. The MAX6501/MAX6502 are offered with hot-temperature thresholds (+35°C to +115°C), assert- ing when the temperature is above the threshold. The MAX6503/MAX6504 are offered with cold-temperature thresholds (-45°C to +15°C), asserting when the tem- perature is below the threshold. The MAX6501–MAX6504 are offered in eight standard temperature versions; contact the factory for pricing and availability of nonstandard temperature versions. They are available in 5-pin SOT23 and 7-pin TO-220 packages. ____________________________Features o ±0.5°C (typical) Threshold Accuracy Over Full Temperature Range o No External Components Required o Low Cost o 30µA Supply Current o Factory-Programmed Thresholds from -45°C to +115°C in 10°C Increments o Open-Drain Output (MAX6501/MAX6503) Push-Pull Output (MAX6502/MAX6504) o Pin-Selectable +2°C or +10°C Hysteresis o SOT23-5 and TO220-7 Packages Low-Cost, +2.7V to +5.5V, Micropower Temperature Switches in SOT23 and TO-220 ________________________________________________________________ Maxim Integrated Products 1 19-1280; Rev 2; 11/99 Ordering Information *These parts are offered in eight standard temperature versions with a minimum order of 2,500 pieces. To complete the suffix information, add P or N for positive or negative trip temperature, and select an available trip point in degrees centigrade. For example, the MAX6501UKP065-T describes a MAX6501 in a SOT23-5 package with a +65°C threshold. Contact the factory for pricing and availability of nonstandard temperature versions (mini- mum order 10,000 pieces). ________________________Applications µP Temperature Monitoring in High-Speed Computers Temperature Control Temperature Alarms Fan Control Selector Guide and Pin Configurations appear at end of data sheet.
