ILC5140/5141/5142

CMOS Multilevel Voltage Detector

General Description

Features

The ILC514X is an innovative, multilevel voltage detector,

designed to monitor the terminal voltage of a power source

and provide up to four independent flags when the voltage

levels drop below designated levels. The ILC514X is

unique in its design because one device can now signal the

user when a discharging battery goes below four (4) differ-

ent threshold voltages and because it requires no external

precision components to monitor these voltage levels. The

open drain flags are asserted when the terminal voltage

goes below their designated thresholds and are de-assert-

ed 140ms after the thresholds are exceeded. Additionally,

the ILC514X has a manual reset pin that allows the system

to assert all flags for a minimum of 200ms.

• Four levels of a single terminal voltage monitored

• No precision external components

• < 10µA Quiescent current

• Available in three output configurations

• Threshold accuracies within ±1%

• Small MSOP10 plastic package

• Factory preset threshold voltages

• Manual reset input pin

• Minimum 140ms delay on reset

Applications

Built using Impala’s prorprietary Analog CMOS process, the

ILC514X is packaged in a spacesaving MSOP10 package.

Quiescent current is below 10µA. The threshold values for

the reset flags are factory set. Alternate values may be dis-

cussed with Impala Product Marketing. Threshold values

are accurate to within ±1%. The device is available in three

output configurations: Open Drain RESET, Push Pull

RESET and Push Pull RESET.
