Local/Remote Temperature Switches in a µMAX Package
General Description
The MAX6687/MAX6688 comprise a remote-junction temperature switch and a local temperature switch in a single package.
The remote-junction switch uses an external P-N junction (typically a diode-connected
transistor on the die of an external CPU, ASIC, or FPGA) as a sensing element to measure the remote temperature.
The remote-junction temperature switch has a factoryprogrammed trip temperature threshold of either +120°C or +125°C.
The local temperature switch has a pin-programmable temperature threshold that is set by connecting pins S1 and S2 to ground, to VDD, or leaving them fl...
