DESCRIPTION
LC9005 is a series of high precision voltage
detector with ultra low current consumption
(500nA typ. at Vdd=3.0V). It can work at very
low voltage, which makes it perfect for
system reset.
LC9005 is composed of high precision
voltage reference, comparator, output driver
and resistor array. Internally preset detect
voltage has a low temperature drift and
requires no external trimming.
One type of output, N-channel open-drain is
available.
LC9005 is available in small size SOT23-3
package which is Pb free.
