DS1233

OPERATION — PUSHBUTTON RESET

The DS1233 provides for a pushbutton switch to be connected to the

output pin. When the DS1233

RST

is not in a reset cycle, it continuously monitors the

signal for a low going edge. If an edge is

RST

detected, the DS1233 will debounce the switch by pulling the

line low. After the internal timer has

RST

expired, the DS1233 will continue to monitor the

line. If the line is still low, the DS1233 will

RST

continue to monitor the line looking for a rising edge. Upon detecting a release, the DS1233 will force the

line low and hold it low for 350ms.

RST

NOTE:

For proper operation with an external pushbutton, a capacitor between 100pF and 0.01mF must be

connected between

and ground. In applications where additional reset current is required, a

RST

minimum capacitance of 500pF should be used, along with a parallel external pull-up resistor of

1kW minimum.
