MAXIM DS1816R-10+T&R

The DS1816 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.

• Automatically restarts a microprocessor after power failure
• Maintains reset for 150ms after VCC returns to an in-tolerance condition
• Reduces need for discrete components
• Precision temperature-compensated voltage reference and voltage sensor
• Accurate 5%, 10% or 20% power monitoring
• 20% tolerance for use with 3V systems
• Low-cost TO-92 or space saving SOT-23 packages available
• Efficient open-drain output with internal 5kΩ pull-up resistor
• Operating temperature -40°C to +85°C
