DS1818R-10+T&R

The DS1818R-10+T&R is an EconoReset Supervisory Circuit with pushbutton. The DS1818 EconoReset uses a precision temperature-compensated reference and comparator 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 returns to an in-tolerance condition, the reset signal is kept in the active state for approximately 150 ms to allow the power supply and processor to stabilize. The DS1818 also monitors a pushbutton on the reset output. If the reset line is pulled low, a reset is generated upon release and the DS1818 output will be held in reset output low for typically 150ms.

• Improves reliability of processor operation - Monitors pushbutton for external override
• Efficient open-drain output with internal 5.5kΩ pull-up resistor saves power and space
• Allows for easy design with no complicated settings
