DS1233A-15+ - Brand New Maxim Integrated Supervisors
-
Description
The DS1233A-15+ is an electronic component model in the supervisors category. It serves as an EconoReset for monitoring two vital conditions of a microprocessor: power supply and external override. 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, initiating a reset to the active state. When VCC returns to an in-tolerance condition, the reset signal remains active for approximately 350ms to allow stabilization of the power supply and processor. The DS1233A-15+ also incorporates pushbutton reset control, debouncing a pushbutton closure and generating a 350ms reset pulse upon release.
