Product Overview

The MAX6831SVUT+T from Maxim Integrated Products is a dual ultralow voltage µP supervisors with manual reset and watchdog timer in 6 pin SOT-23 package. This ultralow voltage microprocessor (µP) supervisory circuit is designed to monitor two power supplies and has manual reset and watchdog input functions. This device asserts a system reset if any of the monitored supplies fall below the pre-programmed thresholds and maintains reset for a minimum timeout period after the supplies rise above the threshold. Microprocessor supervisor significantly improves system reliability and accuracy compared to separate ICs or discrete components. It is guaranteed to be in the correct state for VCC down to +1V. The MAX6831 provide a factory trimmed threshold to monitor a 2nd voltage down to +0.9V. It is used in portable/battery powered equipment, embedded controllers, intelligent instruments, critical µP monitoring and multivoltage systems.
  • Operating voltage range from 1V to 5.5V (TA = 0°C to +85°C) and 1.2V to 5.5V (TA = -40°C to +125°C)
  • Reset timeout period of 200ms at TA = -40°C to +85°C and 320ms at TA = -40°C to +125°C
  • Open-drain active-low reset output
  • 1.6s watchdog timeout period
  • Reset valid down to VCC = +1V
  • Immune to short negative VCC transients, no external components
  • VCC supply current of 10µA at TA = -40°C to +85°C, VCC = +5.5V, no load
  • 2.93V VCC reset threshold at TA = -40°C to +85°C, 1.575V VCC2 reset threshold at TA = -40°C to +85°C
  • Operating temperature range from -40°C to +125°C
  • Critical µP Monitoring; Embedded Controllers; Intelligent Instruments; Multivoltage Systems; Portable/Battery-Powered Equipment
