SGM894B数据手册SGMICRO中文资料规格书

描述 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 5.0V with 0.1V increments. 
In addition, the CD pin of SGM894B has an external capacitor connected to GND, which can adjust the release delay time. Consequently delay time can be set to more than 1s when the delay capacitor (CD) is 1μF. The device is very suitable for applications in power sequencing, reset sequencing and power switching. 
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.
