Ultra Low Power 3 Ld Voltage Supervisors
in SC-70 and SOT-23 Packages
The ISL88001, ISL88002, ISL88003 supervisors are
extremely low power 160nA voltage supervisors that help to
monitor the power supply voltages in a wide variety of
applications. By providing Power-On Reset and supply
voltage supervision in small 3 Ld SC-70 and SOT-23
packages, the ISL88001, ISL88002, ISL88003 devices can
help to lower system cost, reduce board space requirements
and increase the reliability of systems.
The most popular voltage trip points are available for
standard power supplies from 1.8V to 5.0V (see “Ordering
Information” on page 3). These reset threshold voltages are
accurate to within ±1.2% and the reset signal is valid down to
1V. Active high and active low reset outputs are available in
push-pull and open drain configurations (see “Functional
Block Diagrams” on page 2).
The ISL88001, ISL88002, ISL88003 devices are specifically
designed for low power consumption and high threshold
accuracy, making them especially suitable for electronic
devices and portable equipment.
