... Efficient open-drain output with internal 5.5 k pull-up resistor Operating temperature -40°C to +85°C DESCRIPTION The DS1811 EconoReset uses a precision temperature reference and comparator circuit to monitor the status of the power supply (V CC signal is generated which forces reset to the active state. When V the reset signal is kept in the active state for approximately 150 ms to allow the power supply and processor to stabilize ...
