Description

The DS1233M-55+ is an electronic component model in the category of supervisors. It utilizes a precision temperature-compensated reference and comparator circuit to monitor the power supply status. Whenever an out-of-tolerance condition is detected, an internal power-fail signal is generated, forcing a reset to the active state. The reset signal remains active for approximately 350 ms after the power supply returns to an in-tolerance condition, allowing for stabilization of both the power supply and the processor.
