Description

The DS1812R-15+T&R is an electronic component model categorized as Supervisors. It is equipped with a precision temperature reference and comparator circuit that monitors the power supply (VCC) status. When an out-of-tolerance condition is detected, an internal power-fail signal is generated, which forces the reset to the active state. To allow the power supply and processor to stabilize, the reset signal remains active for approximately 150ms when VCC returns to an in-tolerance condition.

Specifications and features

• Automatically restarts a microprocessor after power failure
• Maintains reset for 150ms after VCC returns to an in-tolerance condition
• Reduces the need for discrete components
• Precision temperature-compensated voltage reference and voltage sensor
• Low-cost TO-92 or space-saving surface mount SOT-23 packages available
