Description

The DS1818R-10+T&R is an electronic component model belonging to the category of Supervisors. It utilizes a precision temperature-compensated reference and comparator circuit to monitor the status of the power supply (VCC). When an out-of-tolerance condition is detected, it generates an internal power-fail signal that triggers a reset to the active state. After VCC returns to an in-tolerance condition, the reset signal remains active for approximately 150 ms, allowing the power supply and processor to stabilize.
