D1830/A
OPERATION — POWER MONITOR
The DS1830 provides the functions of detecting out-of-tolerance conditions on a power supply and
warning a processor based system of impending power failure. When V CC is detected as out-of-tolerance
all reset outputs will be forced active. When V CC returns to a valid state , RST1 will remain active for
period of time based on the condition of the TD input. Reset outputs RST2 and RST3 follow RST1 , each
one at the proper delays for the condition of the TD input. All resets will remain in the inactive state
(high) until the next V CC out-of-tolerance condition or pushbutton reset. On power-up all resets are kept
active for an appropriate period determined by the status of the TD input after the power supply inputs
have reached the selected tolerance. This allows the power supply and system power to stabilize before
the reset sequences are released.

OPERATION — TOLERANCE SELECT
The DS1830/A provides a TOL input for individual customization of the DS1830x to specific application
requirements (see Table 1). For the tolerance selection, see Table 1 below. The TOL input is only
sampled while V CC is below the lowest potential trip value and can not be changed after the V CC voltage
exceeds the lowest potential trip value.
