SGM8714B-1

The SGM8714A-1 and SGM8714B-1 are single, nano-power, small size comparators. They are optimized for low voltage operation from 1.6V to 5.5V single supply, and consume only 300nA quiescent current. Both devices are packaged in a space-saving XTDFN package, which is 1mm × 1mm. The combination of these features makes them good choices for smart battery-powered equipment. Meanwhile, the SGM8714A-1 and SGM8714B-1 also have a great trade-off between low power and high speed, whose propagation delay is only 6μs. This results in a continuous system monitoring and quick respond to fault conditions without too much battery power dissipation.

These devices have different output structures. The SGM8714A-1 has a push-pull output structure, which can easily drive the LED, resistive or capacitive load with the ability of sourcing or sinking the current for the level of milliamp. The SGM8714B-1 has an open-drain output structure, which needs an external pull-up resistor to output a high level of VS or a voltage below VS. So it enables conversion from bipolar to single-ended signals and level translation. A clamp diode is designed between the OUT pin and the +VS pin to avoid the SGM8714A-1 and SGM8714B-1 being damaged when the output voltage exceeds the power supply.

The SGM8714A-1 and SGM8714B-1 are both available in a Green XTDFN-1×1-6L package. They are rated over the -40℃ to +125℃ operating temperature range.
