DS1813R-5+T&R

DS1813R-5+T&R is a 5V EconoReset with a pushbutton. The DS1813 EconoReset uses a precision temperature 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 150ms to allow the power supply and processor to stabilize. It also monitors a pushbutton on the reset output. If the reset line is pulled low, a reset is generated upon release and will be held in reset output low for typically 150ms.

• Automatically restarts a microprocessor after power failure
• Monitors pushbutton for external override
• Maintains reset for typically 150ms after VCC returns to an in-tolerance condition
• Reduces need for discrete components
• Precision temperature-compensated voltage reference and voltage sensor
• Efficient open-drain output with internal 5.5Kohm pullup resistor
• Output capacitance is 10pF
• SOT-23 package
• Operating temperature range from -40°C to +85°C
• Reset active time is 150ms typical (VCC = 1.2V to 5.5V, TA = -40°C to +85°C)
