DS1832 - 3.3 Volt Micromonitor Chip

General Description

PBRST TD TOL GND RST RST ST VCC - Pushbutton Reset Input - Time Delay Set - Selects 10% or 20% VCC Detect - Ground - Active High Reset Output - Active Low Reset Output - Strobe Input - Power Supply DESCRIPTION The DS1832 3.3-Volt MicroMonitor monitors three vital conditions for a microprocessor:

Key Features

  • Halts and restarts an out-of-control microprocessor Holds microprocessor in check during power transients Automatically restarts microprocessor after power failure Monitors pushbutton for external override Accurate 10% or 20% microprocessor power monitoring Eliminates need for discrete components 20% tolerance for use with 3.0-volt systems Pin-compatible with the DS1232 Low cost 8-pin DIP, 8-pin SOIC, and space saving µ-SOP packages available Industrial temperature range of -40°C to +85°C PIN A.
