Product Summary

The DS1232LP+ is a Low Power MicroMonitor Chip which monitors three vital conditions for a microprocessor: power supply, software execution, and external override. First, a precision temperature-compensated 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

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.
