DATASHEET
ISL88001, ISL88002, ISL88003
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.

Ground IC reference.
The RST pin is an active-low reset output that is pulled to GND (LOW) when reset is
asserted. The ISL88001 is push-pull while the ISL88002 is open drain.
The RST pin is a push-pull active-high reset output that is pulled to V
DD
(HIGH) when reset
is asserted.

NOTES:
1. For non-standard voltage trip point versions between 1.5V and 5V in 100mV increments, please contact factory for availability.
2. Add “-TK” suffix for 1000 piece Tape and Reel. Please refer to
TB347
for details on reel specifications.
3. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC
J STD-020.
4. For Moisture Sensitivity Level (MSL), please see device information page for
ISL88001, ISL88002, ISL88003.
