ISL88011, ISL88012, ISL88013,

ISL88014, ISL88015

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

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

±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.
