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

custom monitoring of any voltage down to 0.6V. All parts are
specifically designed for low power consumption and high
threshold accuracy.
