SG6521SZ - PC Power Supply Supervisors

Download the SG6521SZ datasheet PDF. This datasheet also covers the SG6521 variant, as both devices belong to the same pc power supply supervisors family and are provided as variant models within a single manufacturer datasheet.

Description

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.

Features

  • 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.
  • Over-Temperature.
