5 Ld Voltage Supervisors with Adjustable
Power-On Reset, Dual Voltage Monitoring
or Watchdog Timer Capability
The ISL88011 through 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.
Unique features on the ISL88013 and ISL88015 include a
watchdog timer with a 51s startup timeout and a 1.6s normal
timeout duration. On the ISL88011 and ISL88014, users can
increase the nominal 200ms Power On Reset timeout delay
by adding an external capacitor to the CPOR 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 4).
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
www.DataSheet4U.com
custom monitoring of any voltage down to 0.6V. All parts are
specifically designed for low power consumption and high
threshold accuracy.
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.
• Both RST and RST Outputs Available
• Adjustable POR Timeout Delay Options
• Watchdog Timer With 1.6s Normal and 51s Startup
Timeout Durations
• Manual Reset Input on All Devices
• Reset Signal Valid Down to VDD = 1V
• 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 Plus Anneal Available (RoHS Compliant)
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
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

provided for information only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification are not implied.
For guaranteed specifications and test conditions, see Electrical Specifications. The guaranteed specifications apply only for the test conditions listed. Some
performance characteristics may degrade when the device is not operated under the listed test conditions.
NOTE:
