DS1834/A/D
Dual EconoReset with Pushbutton
DS1834/A/D
062698 1/7
FEATURES
5 volt power–on reset
3.3 volt power–on reset
Internal power is drawn from higher of either the 5V IN
input or the 3.3V IN input
Excellent for systems designed to operate with dual
power supplies
Asserts resets during power transients
Pushbutton reset input for system override
Maintains reset for 350 ms after V
CC
returns to an in–
tolerance condition
Reduces need for discrete components
Precision temperature–compensated voltage refer-
ence and voltage sensor
8–pin DIP, 8–pin SOIC, and 8–pin

DESCRIPTION
The DS1834 Dual EconoResets monitors three vital
system conditions: 5 volt supply, 3.3 volt supply, and an
external override. First a precision temperature refer-
ence and comparator circuit monitors the status of the
5 volt supply and the 3.3 volt supply. When an out–of–
tolerance condition is detected, an internal power fail
signal is generated which forces the reset of the affected
supply to an active state.
Lastly, the DS1834 supports an external reset via an
internally debounced pushbutton input. When the push-
button is pulled low both resets will be asserted for
approximately 350 ms after the pushbutton is released.
