DS1814C - Brand New SAMTEC Supervisors
-
Description
The DS1814C is a 5-Volt MicroMonitor and the DS1819 is a 3.3V MicroMonitor that is used to monitor three essential conditions for a microprocessor: power supply, software execution, and external override. It includes a precision temperature compensated reference and comparator circuit to monitor the status of VCC. When an out-of-tolerance condition occurs, an internal power-fail signal is generated, which activates the reset(s). The reset signal is kept in the active state for a minimum of 140ms to allow the power supply and processor to stabilize when VCC returns to an in-tolerance condition.
Specifications and features
The DS1814C/DS1819 has the following specifications and 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% (3V only) microprocessor power monitoring
- Eliminates the need for discrete components
- 20% tolerance for use with 3.0V systems
- Pin- and function-compatible with the MAX823/24/25 products
- Low cost SOT-23-5 package
- Industrial temperature range: -40C to +85C
Application Scenarios
The DS1814C/DS1819 can be used in various scenarios, including but not limited to:
- Microprocessor-based systems
- Embedded systems
- Industrial control systems
- Power supply monitoring
- Hardware watchdog timer
Comparison
The DS1814C/DS1819 offers several advantages:
- Precision temperature compensated reference and comparator circuit
- Automatic restart after power failure
- Compatibility with MAX823/24/25 products
- Low cost and compact SOT-23-5 package
However, it should be noted that the DS1814C/DS1819 has a 20% tolerance for use with 3.0V systems, which may not be suitable for all applications.
