SG6521 Datasheet (Fairchild Semiconductor) - PC Power Supply Supervisors

SG6521, PC Power Supply Supervisors

The SG6521 is designed to provide the supply voltage, current supervisor, remote on/off (PSON), power good (PGO) indicator, and fault protection (FPO) functions for switching power systems.

For supervisory functions, it provides the over-voltage protection (OVP) for 3.3V, 5V, and two 12V; overcurren
