Product Summary
The DS1812R-5 is a 5V EconoReset with Push-Pull Output. The DS1812R-5 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 of DS1812R-5 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
DS1812R-5 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
DS1812R-5 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)Accurate 5%, 10% or 20% power monitoring; (6)Low-cost TO-92 or space saving surface-mount SOT-23 packages available; (7)Push-pull output for low current operation; (8)Operating temperature -40℃ to +85℃.
