Overview

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; overcurrent protection (OCP) for 3.3V, 5V, and two 12V; under-voltage protection (UVP) for 3.3V, 5V, and two 12V.

  • Two 12V Sense Input Pins: VS12 and VS12B
  • Over-Voltage Protection (OVP) for 3.3V, 5V, and two 12V
  • Over-Current Protection (OCP) for 3.3V, 5V, and two 12V
  • Under-Voltage Protection (UVP) for 3.3V, 5V, and two 12V
  • Open-Drain Output for PGO and FPO Pins
  • 300ms Power-Good Delay
  • 2.8ms PSON Control to FPO Turn-off Delay
  • 48ms PSON Control Delay
  • No Lock-up During the Fast AC Power On/Off
  • Wide Supply Voltage Range: 4V to 15V
