Data Sheet

FN8093.4

5 Ld Voltage Supervisors with Adjustable

Power-On Reset, Dual Voltage Monitoring

or Watchdog Timer Capability

The ISL88011, ISL88012, ISL88013, ISL88014, 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

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” 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.

Features

• Single/dual voltage monitoring supervisors

• Fixed-voltage options allow precise monitoring of +2.5V,

+3.0V, +3.3V, and +5.0V power supplies

• Dual supervisor has one fixed voltage input and another

that is user-adjustable down to 0.6V.

• Both RST and RST outputs available

• Adjustable POR timeout delay options

• Watchdog timer with 1.6s normal and 51s start-up timeout

durations

• Manual reset input on all devices

• Reset signal valid down to V

= 1V

• Accurate ±1.5% voltage threshold

• Immune to power-supply transients

• Ultra low 5.5µA supply current

• Small 5 Ld SOT-23 Pb-Free package

• Pb-Free (RoHS Compliant)

Applications

• Process control systems

• Intelligent instruments

• Embedded control systems

• Computer systems

• Critical µP and µC power monitoring

• Portable/battery-powered equipment

• PDA and handheld PC devices

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
