DESCRIPTION
The SGM880xQ is a high accuracy voltage detector with very low supply current. It can be used under CMOS-based 36V input conditions and the absolute maximum voltage of supply voltage can come up to 45V, which can prevent circuit breakdown caused by transient over-voltage pulses. This device has a simple structure with a voltage reference, a comparator with hysteresis, a series of resistor divider and an N-channel output transistor.
The SGM880xQ has very low supply current. It can monitor voltage rails ranging from 2.3V to 12V with ±0.7% accuracy. The output pin (DOUT) is an N-channel active-low open-drain output.
The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
The SGM880xQ is available in a Green SOT-23-5 package. Use of this package achieves high-density mounting on boards.
