ISL88014, ISL88015

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 start-up timeout and a 1.6s

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” 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.
