PIN DESCRIPTION PIN l Ground PIN 2 Reset PIN 3 Vcc PIN 4 Ground (SOT-223 0nly) DESCRIPTION The DS1833 EconoReset uses 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, an internal power fail signal is generated which forces reset to the active (high) state. When Vcc returns to an in- tolerance condition, the reset signal is kept in the active state for approximately 350 ms to allow the power supply and processor to stabilize.
