MAX6504 - Low-Cost / +2.7V to +5.5V / Micropower Temperature Switches

General Description

The MAX6501

MAX6504 low-cost, fully integrated temperature 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.

Key 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 MAX6501.

19-1280; Rev 2; 11/99 Low-Cost, +2.7V to +5.5V, Micropower Temperature Switches in SOT23 and TO-220 ________________General Description The MAX6501–MAX6504 low-cost, fully integrated temperature 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 supply current. Hysteresis is pin-selectable at +2°C or +10°C.
