Data Sheet
December 4, 2015
The ISL88011, ISL88012, ISL88013, ISL88014, ISL88015
family of devices offer both fixed and/or adjustable
voltage-monitoring that combine popular functions such as
Power-On reset control, watchdog timer, supply voltage
supervision, and manual reset assertion in a small 5 Ld
SOT-23 package.
Features
• Single/dual voltage monitoring supervisors
• Fixed-voltage options allow precise monitoring of +2.5V,
+3.0V, +3.3V, and +5.0V power supplies
• Dual supervisor has one fixed voltage input and another
that is user-adjustable down to 0.6V.
Unique features on the ISL88013 and ISL88015 include a
watchdog timer with a 51s start-up timeout and a 1.6s
normal timeout duration. On the ISL88011 and ISL88014,
users can increase the nominal 200ms Power-On reset
• Both RST and RST outputs available
• Adjustable POR timeout delay options
timeout delay by adding an external capacitor to the C
• Watchdog timer with 1.6s normal and 51s start-up timeout
durations
POR
pin. Both fixed and adjustable voltage monitors are provided
by the ISL88012. Complementary active-low and active-high
reset outputs are available on the ISL88011, ISL88012 and
ISL88013 devices. All devices provide manual reset
capability (see “Product Features Table” on page 5).
• Manual reset input on all devices
• Reset signal valid down to V
= 1V
DD
• Accurate ±1.5% voltage threshold
• Immune to power-supply transients
• Ultra low 5.5µA supply current
• Small 5 Ld SOT-23 Pb-Free package
• Pb-Free (RoHS Compliant)
Seven preprogrammed reset threshold voltages accurate to
±1.5% over temperature are offered (see “Ordering
Information” on page 3). The ISL88012, ISL88014 and
ISL88015 have a user-adjustable voltage input available for
custom monitoring of any voltage down to 0.6V. All parts are
specifically designed for low power consumption and high
threshold accuracy.
Applications
• Process control systems
• Intelligent instruments
• Embedded control systems
• Computer systems
• Critical µP and µC power monitoring
• Portable/battery-powered equipment
• PDA and handheld PC devices

NOTES:
ISL88011 Evaluation Card
ISL88013 Evaluation Card
ISL88014 Evaluation Card
1. 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.
2. The voltage trip point can be adjusted to be greater than 0.6V using 2 external resistors. By default, the VTHVMON trip point is 0.6V if no external
resistors are used.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL88011, ISL88012, ISL88013, ISL88014, ISL88015. For more
information on MSL please see techbrief TB363.

The ISL88011, ISL88012, ISL88013, ISL88014, ISL88015
devices provide those functions needed for critical voltage
monitoring. These features include Power-On Reset control,
customizable supply voltage supervision, Watchdog Timer
capability, and manual reset assertion. By integrating all of
these features into a small 5 Ld SOT-23 package and using
only 5.5µA of supply current, the ISL88011, ISL88012,
ISL88013, ISL88014, ISL88015 devices can assist in lowering
system cost, reducing board space requirements, and
increasing the reliability of a system.

Manual Reset
Watchdog Timer
The manual reset input (MR) allows the user to trigger a reset
by using a push-button switch. The MR input is an active-low
debounced input. By connecting a push-button directly from
MR to ground, the designer adds manual system reset
capability (see Figure 4). Reset is asserted if the MR pin is
pulled low to less than 100mV for 1µs or longer while the push-
button is closed. After MR is released, the reset outputs remain

monitoring the WDI input pin. The microprocessor must

otherwise the reset signal is asserted (see Figure 5). Internally,
the 1.6s timer is cleared by either a reset or by toggling the
WDI input.
Besides the 1.6s default timeout during normal operation,
these devices also have a longer 51s timeout for start-up.
During this time, a reset cannot be asserted due to the WDI not
being toggled. The longer delay at power-on allows an
operating system to boot, an FPGA to initialize, or the system
software to initialize without the burden of dealing with the
