Product Summary
The DS1814BR-5/T is a kind of 5-Volt MicroMonitor. The device monitors three vital conditions for a microprocessor: power supply, software execution, and external override. First, a precision temperaturecompensated reference and comparator circuit monitor the status of VCC. When an out-of-tolerance condition occurs, an internal power-fail signal is generated which forces the reset(s) to an active state. When VCC returns to an in-tolerance condition, the reset signal is kept in the active state for a minimum of 140ms to allow the power supply and processor to stabilize.
Parametrics
Absolute maximum ratings: (1)Voltage on VCC Pin Relative to Ground: -0.5V to +7.0V; (2)Voltage on I/O Relative to Ground: -0.5V to VCC + 0.5V; (3)Operating Temperature Range: -40鈩?to +85鈩? (4)Storage Temperature Range: -55鈩?to +125鈩? (5)Soldering Temperature: 260鈩?for 10 seconds.
Features
Features: (1)Halts and restarts an out-of-control microprocessor; (2)Holds microprocessor in check during power transients; (3)Automatically restarts microprocessor after power failure; (4)Monitors pushbutton for external override; (5)Accurate 5%, 10%, or 20% (3V only) microprocessor power monitoring; (6)Eliminates the need for discrete components; (7)20% tolerance for use with 3.0V systems; (8)Pin- and function-compatible with the MAX823/24/25 products; (9)Low cost SOT-23-5 package; (10)Industrial temperature range: -40鈩?to +85鈩?
