5-Pin Voltage Supervisors with Adjustable
Power-On Reset, Dual Voltage Monitoring
or Watchdog Timer Capability
The ISL88011 - 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-pin SOT23 package.
Unique features on the ISL88013 and ISL88015 include a
watchdog timer with a 51sec startup timeout and a 1.6sec
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).
Seven preprogrammed reset threshold voltages accurate to
卤1.5% over temperature are offered (see Ordering
Information). 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.
