Product Details

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.

Halts and restarts an out-of-control microprocessor
Holds microprocessor in check during power transients

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
