Dual-Output Remote-Junction Temperature Switches

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 (THIGHand TLOW). THIGHasserts a logic signal when the remote temperature crosses the factory-programmed, +120°C, or +125°C upper trip threshold. TLOWis 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.THIGHis an open-drain, active-low output for both the MAX6685 and the MAX6686. TLOWis 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
