MAX6685 - Dual-Output Remote-Junction Temperature Switches

General Description

MAX6685/MAX6686 are dual-output temperature switches that use an external diode-connected transistor as a sensing element.

These devices have two logic outputs (THIGH and TLOW).

Key Features

  • o Pin-Programmed Lower Temperature Threshold from +40°C to +80°C or +75°C to +115°C (5°C Increments) o Preset Upper Threshold: +120°C or +125°C o Open-Drain, Active-Low Output for Upper Temperature Alarm o CMOS Push-Pull, Active-High or Open-Drain, Active-Low Output for Lower Temperature Alarm o 1.5°C Accuracy o 3.0V to 5.5V, 200µA Supply o 8-Pin µMAX Package MAX6685/MAX6686.

www.DataSheet4U.com 19-2459; Rev 2; 4/03 Dual-Output Remote-Junction Temperature Switches General Description MAX6685/MAX6686 are dual-output temperature switches that use an external diode-connected transistor as a sensing element. These devices have two logic outputs (THIGH and TLOW). THIGH asserts a logic signal when the remote temperature crosses the factory-programmed, +120°C, or +125°C upper trip threshold. TLOW is asserted when the remote temperature exceeds the lower threshold, which is controlled by pins S1 and S2. The lower thresholds are available in two ranges in 5°C increments. The two ranges are +40°C to +80°C and +75°C to +115°C. Hysteresis for both outputs to be deasserted is typically 5°C. THIGH is an open-drain, active-low output for both the MAX6685 and the MAX6686.
