SG2543 Overview

Key Specifications

Package: SOIC
Mount Type: Surface Mount
Pins: 16
Max Voltage (typical range): 40 V

Description

This monolithic integrated circuit contains all the functions necessary to monitor and control the output of a sophisticated power supply system. Over-voltage (O.V.) sensing with provision to trigger an external SCR “crowbar” shutdown; an under-voltage (U.V.) circuit which can be used to monitor either the output or to sample the input line voltage; and a third op amp/comparator usable for current sensing (C.L.) are all included in this IC, together with an independent, accurate reference generator.

Key Features

  • Over-Voltage, Under-Voltage, and Current Sensing Circuits all included
  • Reference Voltage Trimmed to 1% Accuracy
  • SCR "Crowbar" Drive of 300mA
  • Programmable Time Delays
  • Open-Collector Outputs and Remote Activation Capability
