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 C

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.
