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 * 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 https://elecena.pl/product/22301043/micromonitor-chip 2022-12-25 https://elecena.pl/product/22301043/micromonitor-chip 2025-01-20
