Description

The DS1811R-10+ is an electronic component model that falls under the category of supervisors. It utilizes a precision temperature reference and comparator circuit to monitor the status of the power supply (VCC).

When an out-of-tolerance condition is detected, the DS1811R-10+ generates an internal power-fail signal, resulting in a forced reset to the active state. After VCC returns to an in-tolerance condition, the reset signal is kept active for approximately 150 ms to allow the power supply and processor to stabilize.

Specifications and features

• Automatically restarts a microprocessor after power failure
• Maintains reset for 150 ms after VCC returns to an in-tolerance condition
• Reduces the need for discrete components
• Precision temperature-compensated voltage reference and voltage sensor
• Available in low-cost TO-92 or space-saving SOT-23 packages
• Efficient open-drain output with internal 5.5 kΩ pull-up resistor
• Operating temperature: -40°C to +85°C

Application Scenarios

The DS1811R-10+ is commonly used in various applications where the monitoring and control of power supply is critical. This includes but is not limited to power management systems, industrial automation, automotive electronics, and embedded systems.
