Datasheet
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.
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.
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:
RESET and Push Pull RESET.
