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.

Pin Descriptions
RST
The ISL88003 push-pull RST output is set to VDD (HIGH)
whenever the device is first powered up or VDD falls below
its respective minimum voltage sense level.
RST
The RST output functions identically to the complementary
RST output. On the ISL88001, this is a push-pull output. On
the ISL88002, it is an open drain output that is pulled to GND
(LOW) when reset is asserted. Suggested pull-up RST
resistor values are in the range of 5kto 100k.
VDD
The VDD pin is the power supply terminal. The voltage at this
pin is compared against an internal factory-programmed
voltage trip point, VTHVDD. A reset is first asserted when the
device is initially powered up to ensure that the power supply
has stabilized. Thereafter, reset is again asserted whenever
VDD falls below VTHVDD. The device is designed with
hysteresis to help prevent chattering due to noise.
device asserts a reset signal (RST = LOW or RST = HIGH)
to a µP/µC if this voltage is less than the preset voltage trip
point. The reset signal prevents system operation during a
power failure or brownout condition. This reset signal
remains asserted until VDD exceeds the voltage threshold
setting for the reset time delay period tPOR. See Figure 2.

FIGURE 1. TYPICAL APPLICATION DIAGRAM
Principles of Operation
The ISL88001, ISL88002, ISL88003 devices provide a low
power, high accuracy solution for those voltage monitoring
applications needing supply voltage supervision with power
reset control. By integrating these features into small 3 Ld
SC-70 and 3 Ld SOT-23 packages and consuming as little
as 160nA of supply current, these devices can lower system
cost and reduce board space requirements.
Low Voltage Monitoring
During normal operation, the ISL88001, ISL88002,
ISL88003 devices monitor the voltage level of VDD. The
