DS1833 Overview
PIN 1 Ground PIN 2 Reset PIN 3 PIN 4 VCC Ground (SOT-223 only) DESCRIPTION The DS1833 EconoReset uses a precision temperature pensated reference and parator circuit to monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power fail signal is generated which forces reset to the active (high) state. When VCC returns to an intolerance condition, the reset signal is...
