DS1834AS+ – Dual Voltage Supervisor IC for 3.3V/5V Systems – Analog Devices
The DS1834AS+ from Analog Devices is a high-reliability dual-voltage supervisor IC designed to monitor 3.3V and 5V power rails in mission-critical systems. Part of the EconoReset™ series, this CMOS device ensures stable microprocessor operation during power-up, brownout, and power-down scenarios with its precise monitoring and reset control. PCX supplies this industrial-grade component with guaranteed stock and rapid delivery.
Key Features
Voltage Monitoring: Dual thresholds at 3.3V and 5V
Output Configuration: Open-drain/open-collector with active-low reset
Reset Timeout: 200ms minimum delay
Operating Range: Industrial temperature (-40°C to 85°C)
Package: Surface-mount 8-SOIC (3.90mm width)
Low-Power Design: CMOS technology efficiency
Technical Specifications
This multi-voltage supervisor IC monitors two independent power rails simultaneously. The device asserts a reset signal when either voltage drops below its fixed threshold (3.3V or 5V), maintaining system integrity during unstable power conditions. Featuring an open-drain output stage with active-low reset logic, it interfaces seamlessly with microcontrollers. The industrial temperature rating (-40°C to 85°C) ensures performance in harsh environments. Housed in a compact 8-SOIC package, it’s ideal for space-constrained designs.
Typical Applications
Microcontroller/Microprocessor reset circuits
Industrial automation control systems
Server and networking equipment power management
Embedded computing modules
Automotive electronics subsystems
