MAX6686AU75L+

Price range: $1.64 - $5.93

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. TLOW is a CMOS push-pull, active-high output for the MAX6685 and is an open-drain, active-low output for the MAX6686. They are available in a space-saving 8-pin µMAX package.ApplicationsCPU Temperature ProtectionFan ControlFPGA Temperature ProtectionMultichip Modules
