The SGM90810 is an 8-channel system monitor especially designed for monitoring complicated system status. The power supply voltage range is from 3V to 5.5V. By configuring the internal registers, the signal input mode can be single-ended or pseudo-differential. The SGM90810 is equipped with a temperature sensor inside, built-in digital comparators and an interrupt output pin, which provides flexibility to monitor each channel and generate alarm signals when the input exceeds the thresholds. The SGM90810 also integrates an internal reference, which makes this device a complete single chip solution for system monitor.
