DS1232：MicroMonitor芯片

The DS1232 MicroMonitor™ Chip 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 250ms to allow the power supply and processor to stabilize.

关键特性 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% or 10% microprocessor power supply monitoring Eliminates the need for discrete components Space-saving, 8-pin mini-DIP Optional 16-pin SOIC surface mount package Industrial temperature -40°C to +85°C available, designated N
