Maxim DS1233AZ-10/TR/C01, 1-Wire Supervisor IC

The Maxim DS1233AZ-10/TR/C01 is a 1-Wire Supervisor IC.The DS1233A EconoReset monitors two vital conditions for a microprocessor power supply and external override. A precision temperature-compensated reference and comparator circuit are used to monitor the status of the power supply. When an out-of-tolerance condition is detected, an internal power fail signal is generated which forces reset to the active state. When voltage returns to an in-tolerance condition, the reset signal is kept in the active state for approximately 350ms to allow the power supply and processor to stabilize. The second function of the DS1233A is pushbutton reset control. The DS1233A debounces a push button closure and will generate a 350ms reset pulse upon release.
