Description

The DS1232LP/ DS1232LPS Low Power 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 250 ms to allow the power supply and processor to stabilize. DS1232LPS Features • Super low-power version of DS1232• 50 A quiescent current• Halts and restarts an out–of–control microprocessor• Automatically restarts microprocessor after power failure• Monitors pushbutton for external override• Accurate 5% or 10% microprocessor power supply monitoring• 8–pin DIP, 8–pin SOIC or space saving m–SOP package available• Optional 16–pin SOIC package available• Industrial temperature –40°C to +85°C available, designated N
