DESCRIPTION

The DS1233M EconoReset uses a precision temperature-compensated reference and comparator circuit to

monitor the status of the power supply (V_CC). When an out-of-tolerance condition is detected, an internal

power-fail signal is generated which forces reset to the active (low) state. When V_CCreturns to an

intolerance condition, the reset signal is kept in the active state for approximately 350 ms to allow the

power supply and processor to stabilize.
