DS1811 Overview
TO-92 1 RST 2 VCC 3 GND Active Low Reset Output Power Supply Ground SOT-23 1 RST 2 VCC 3 GND Active Low Reset Output Power Supply Ground DESCRIPTION The DS1811 EconoReset uses a precision temperature 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 state. When VCC...
