SGM894B

Voltage Detector with Delay Time Adjustable

GENERAL DESCRIPTION

FEATURES

The SGM894B is a low power consumption voltage

detector with high accuracy detection. The miniature

device offers tremendous flexibility with an adjustable

threshold that is available from 1V to 5V with 0.1V

increments. The SGM894B has an external capacitor-

adjustable time delay. The device is ideal for use in

power-supply sequencing, reset sequencing, and power-

switching applications.

● High Accuracy Detection: ±1% (TYP)

● Low Power Consumption:0.4μA (TYP) at V_IN= 1V

● Detection Voltage Range: 1V to 5V (0.1V Increments)

● Operating Voltage Range: 1V to 6V

● Detection Voltage Temperature Coefficient:

±40ppm/℃ (TYP)

● N-Channel Open-Drain Output

● Built-in Delay Circuit: Adjustable Delay Time

● -40℃ to +125℃ Operating Temperature Range

● Available in Green XTDFN-0.9×1.2-4L and

SC70-4 (R) Packages

Moreover, the release delay time can be adjusted by

the external capacitor which is connected to the C_Dpin.

Consequently, the delay time can be set to more than

1s when C_Dcapacitor is 1μF. Open-drain output

configuration is available.

TYPICAL APPLICATION

The SGM894B is available in Green XTDFN-0.9×1.2-4L

and SC70-4 (R) packages. They are specified over the

-40℃ to +125℃ operating temperature range.
