5 Ld Voltage Supervisors with Adjustable Power-On Reset, Dual Voltage
Monitoring or Watchdog Timer Capability
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.
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
timeout delay by adding an external capacitor to the C
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).
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.

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.
