Maxim Integrated DS1705ESA
- Part Number:
- DS1705ESA
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3267942-DS1705ESA
- Description:
- IC MICROMONITOR 5V 5% 8-SOIC
- Datasheet:
- DS1705ESA
Description
The DS1705/DS1706 3.3- or 5.0-Volt MicroMonitor monitors three vital conditions for a microprocessor: power supply, software execution, and external override. A precision temperature compensated reference and comparator circuit monitor the status of Voc at the device and at an upstream point for maximum protection. When the sense input detects an out-of-tolerance condition, a non-maskable interrupt is generated. As the voltage at the device degrades, an internal power fail signal is generated which forces the microprocessor into reset.
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 5%, 10% or 20% resets for 3.3V systems and 5% or 10% resets for 5.0V systems
Eliminates the need for discrete components
3.3V 20% tolerance for use with 3.0V systems
Pin-compatible with the MAXIM MAX705/MAX706 in 8-pin DIP, 8-pin SOIC, and μ-SOP
8-pin DIP, 8-pin SOIC and 8-pin μ-SOP packages
Industrial temperature range -40°C to 85°C
Applications
Microprocessor reset and watchdog timer
Power supply monitoring
External override for microprocessor reset
Industrial control systems
Automotive electronics
Medical electronics
