Product Summary
The DS1811R-15 is a 5V EconoReset with Open Drain Output. The DS1811R-15 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 150 ms to allow the power supply and processor to stabilize.
Parametrics
DS1811R-15 absolute maximum ratings: (1)Voltage on VCC Pin Relative to Ground -0.5V to +7.0V; (2)Voltage on RST Relative to Ground -0.5V to VCC +0.5V; (3)Operating Temperature -40℃ to +85℃; (4)Storage Temperature -55℃ to +125℃; (5)Soldering Temperature 260℃ for 10 seconds.
Features
DS1811R-15 features: (1)Automatically restarts a microprocessor after power failure; (2)Maintains reset for 150 ms after VCC returns to an in-tolerance condition; (3)Reduces need for discrete components; (4)Precision temperature-compensated voltage reference and voltage sensor; (5)Low-cost TO-92 or space saving SOT-23 packages available; (6)Efficient open-drain output with internal 5.5 kΩ pull-up resistor; (7)Operating temperature -40 to +85℃.
