Product Summary
The DS1232LP+ Low Power MicroMonitor Chip monitors three vital conditions for a microprocessor: power supply, software execution, and external over-ride. The DS1232LP+ has an internal timer that forces the reset signals to the active state if the strobe input is not driven low prior to timeout. The DS1232LP+ detects out-of-tolerance power supply conditions and warns a processor-based system of impending power failure.
Parametrics
DS1232LP+ 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.
