SGM860 Quad Supply Voltage Supervisors with Adjustable Delay and Watchdog Timer
GENERAL DESCRIPTION
FEATURES
The SGM860 is a family of supply voltage supervisors (SVSs). It has four channels and each one can monitor a power rail with a high threshold accuracy of 0.35% typically. It also features very low quiescent current of 6μA (TYP).
Among the supply voltage supervisor (SVS-x, x = 1, 2, 3, 4) circuits, four power rails are higher than 0.4V and one power rail is less than 0.4V (even with negative voltage). Once the SENSEy (y = 1, 2, 3, 4L, 4H) input voltage goes down below the configurable threshold, a nRESETx signal can be asserted by each SVS-x. The threshold of each SVS-x can be configured by the external resistors.
