GENERAL DEscriptION

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 se, reset se, and power-switching applications.

Moreover, the release delay time can be adjusted by the external capacitor which is connected to the CD pin. Conse, the delay time can be set to more than 1s when CD capacitor is 1μF. Open-drain output configuration is available.

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.
