SGM882xQ
Automotive Grade36V Window Voltage Detector with Internal Reference for OV/UV Monitoring for Automotive Applications
The SGM882xQ is a 2.3V to 36V wide-supply voltage window detector for over-voltage (OV) and under-voltage (UV) detection. It features two high-accuracy comparators with an internal reference voltage of 400mV and two open-drain reset outputs, capable of handling up to 36V. The device can function as either two independent voltage monitors or as a window voltage detector adjusted via external resistors.
If the IN1 voltage falls below the negative threshold, nRESET1 is pulled low. And if the IN1 voltage rises over the positive threshold, nRESET1 is pulled high.
If the IN2 voltage rises over the positive threshold, nRESET2 is pulled low. And if the IN2 voltage falls below the negative threshold, nRESET2 is pulled high.
To prevent false triggering and ensure stable output operation of the device, the two comparators feature built-in hysteresis for noise rejection.
The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
The SGM882xQ is available in a Green SOT-23-6 package. It operates in the temperature range of -40℃ to +125℃.
