Product Summary
The DS1232LPS-2+T Low Power MicroMonitor Chip monitors have three vital conditions for a microprocessor: power supply, software execution, and external over-ride. First, a precision temperaturecompensated reference and comparator circuit monitors the status of VCC. When an out-of-tolerance condition occurs, an internal power-fail signal is generated which forces reset to the active state. When VCC returns to an in-tolerance condition, the reset signals are kept in the active state for a minimum of 250 ms 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: 0℃ to 70℃; (4)Operating Temperature (Industrial Version): -40℃ to +85℃; (5)Storage Temperature: -55℃ to +125℃; (6)Soldering Temperature: 260℃ for 10 seconds.
Features
