ISL88001, ISL88002, ISL88003

Ultra Low Power 3 Ld Voltage Supervisors in SC-70 and SOT-23 Packages

DATASHEET

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.
