T A = –30 to +80 C, Case 1213, 1212
circuits that are specifically designed for use with battery
powered microprocessor based systems, where extended
battery life is required. A choice of several threshold voltages
from 0.9 V to 4.5 V are available. These devices feature a very
low quiescent bias current of 0.8 A typical.
reference, a comparator with precise thresholds and built–in
hysteresis to prevent erratic reset operation, a choice of out-
put configurations between open drain or complementary
MOS, and guaranteed operation below 1.0 V with extremely
low standby current. These devices are available in either
SOT–89 3–pin or SOT–23 5–pin surface mount packages.
