SGM90810
12-Bit, 8-Channel, Digital System Monitor with Temperature Sensor, Internal/External Reference, and I2C Interface
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.
The SGM90810 system monitor has a true 12-bit sigma-delta ADC internally with I2C interfaces. The interface supports the Standard Mode (100kbps) and the Fast Mode (400kbps). The analog filters on the I2C bus provide excellent noise resistance performance. The SDA and SCL of I2C have a timeout reset function to prevent I2C bus locking. The SGM90810 provides a flexible sequencer for controlling channel conversions. The data conversion results of each channel is stored in independent registers. And each channel can be independently shut down to save power.
The SGM90810 is available in a Green TSSOP-16 package. It operates over the operating temperature range of -40℃ to +125℃.
